The secret sauce on the ROKR E8 is its keyboard, which changes when it’s used as a phone, music device and camera.

As technology continues to shrink, more features are being packed into these small mobile devices, making navigation and ease-of-use more important. This week, I tested the Motorola ROKR E8, which costs $199 with a two-year T-Mobile service agreement and makes a real attempt to be more user-friendly. The device, which comes out on July 7, isn’t much bigger than a typical cellphone but its standout feature is its keyboard, which dynamically changes to accommodate whatever you’re doing at the time, revealing only buttons that would be of use to that particular function.

The surface of the ROKR E8 has no physical keys at all. In its off or resting state, in fact, it’s just a black surface with rows of tiny, unlabeled bumps. But this surface is actually divided into two: The top half works like a typical cellphone display while the bottom half projects virtual keys onto its surface and uses the rows of bumps to give these keys a physical presence.

When making a call or sending a text message, the ROKR’s surface displays a regular phone keypad. But as soon as a music shortcut button is pressed, the surface morphs into five buttons for music navigation: play/pause, seek forward, seek backward, shuffle and repeat. Pressing another shortcut button to start the ROKR’s camera mode shows four buttons for zooming in or out, switching to playback mode or changing to video. Motorola calls this its ModeShift technology. Though the lower half of the ROKR can be considered a touch device, objects can’t be manipulated with gestures like pinching or dragging as with the Apple iPhone’s multitouch screen.

Overall, I found that the ROKR E8’s dynamic keyboard gave me a real advantage in figuring out how to use the multi-functionality of the phone. Its changing keyboard eliminated a lot of guesswork and time that I may have spent hunting through menus for a command. And true to its name, the ROKR (pronounced “rocker”) is focused on its music phone functionality with an FM radio, a neatly organized music menu and a speaker that has convincingly simulated surround-sound effects.

But this ROKR didn’t always jam out in perfect pitch. A touch-sensitive semicircle in the center is meant to make scrolling through long lists easier — much like Apple Inc.’s iPod wheel. But because this tool on the ROKR isn’t a full circle, scrolling felt unsatisfying. You also can’t buy songs with the ROKR, or even mark songs for purchasing later on a PC.

And while the morphing buttons look futuristic and hip, I experienced a few instances when the phone was slow to react after I touched a button, as when I touched the seek forward button while listening to music or when I chose to open an MMS message I sent to a friend.

Twenty-two tiny bumps dot half of the ROKR’s surface, and the surface below each bump vibrates when it’s touched to provide sensory feedback. Nothing is ever physically pressed down, though the vibration response leads you to think otherwise.

A smart switch on the side can be held down to turn it on or off, or switched into the upward position to lock the device, preventing accidental calls or battery drain.

The ROKR E8 runs on T-Mobile’s GPRS/EDGE connection, which felt sluggish at times. And not even the dynamic keyboard on this device could help make email or instant messaging easier.

It has a two-megapixel still camera with an 8x digital zoom that can change into video-camera mode in one step. Two gigabytes of memory are built into the ROKR, and more memory can be added via a microSD card slot, which is hidden beneath a back panel. A one-gigabyte microSD card comes with the ROKR. Without this card, the internal memory will hold about 1,500 songs.

With help from a USB cord and Windows Media Player 11, I transferred over 200 MP3s onto my ROKR. Album art that transferred with my songs appeared on-screen as songs played, and the speaker gave off a powerful sound. Built-in stereo Bluetooth can send tunes to Bluetooth-enabled stereo speakers, and it took me just a few seconds to pair my ROKR with Motorola’s EQ5 speakers.

A preloaded program by Shazam lets users hold the ROKR up to any speaker playing a song, and in 30 seconds, identifies the track title, artist, and album art. I held the ROKR up to my alarm clock radio and it worked perfectly. But once these songs are recognized, the track data can’t be used to buy the song or even to transfer a request to buy that song to a PC for buying online at another time.

The ROKR’s FM radio will work only if its included stereo headset is plugged in because the headset has the radio antenna. But once the headset is plugged in, the radio will play via the ROKR’s speaker.

The ROKR E8 has an audio technology called Crystal Talk, which Motorola says allows your phone to perform better in loud environments. Even if the person on the other end of your phone is in a noisy place, the company says Crystal Talk will raise the volume to improve the call. I tested this by speaking to someone on the ROKR while turning a hairdryer on beside the phone. I then used a regular Razr cellphone. The person on the other end said that the ROKR sounded slightly, but noticeably, better.

Motorola’s ROKR E8 is a head-turning phone with many built-in advances that give it a smarter interface. One might wonder what other ModeShift functions the company will integrate into its devices in the future, such as a full QWERTY keyboard. The overall idea of a dynamic keyboard is a step ahead for small devices. It forces the phone to work more intuitively and improves navigation while looking stylishly sleek at the same time.

Basic cellphones, unlike larger BlackBerrys or iPhones, are still favored by plenty of users who would rather carry a small device that feels more comfortable to hold to the ear. But the phones’ size involves a trade-off: cramped keypads and clumsy software that can make these phones a pain to use for anything other than calls.

As technology continues to shrink, more features are being packed into these small mobile devices, making navigation and ease-of-use more important. This week, I tested the Motorola ROKR E8, which costs $199 with a two-year T-Mobile service agreement and makes a real attempt to be more user-friendly.

When I was a child, trips to my grandmother’s house meant playing with a magical toy: her Polaroid camera. Grammy was confined to a wheelchair at a time when most people drove to the drugstore to get film developed, so this instant camera worked as her portable darkroom. She lined her “Polaroids” up on the kitchen table for us to see, and encouraged us to snap photos to add to the collection. I was fascinated by the white sheets churned out by each press of the camera’s shutter button and the images that slowly appeared on these prints moments later.

Polaroid’s $150 PoGo is an inkless printer that churns out 2×3-inch photos sent to it via Bluetooth-enabled devices or from plugged-in digital cameras.

Just this year, Polaroid Corp. said it would cease production of its “magical” cameras. But this week, I had the chance to test the company’s latest attempt at relevance in our digital world: the $150 Polaroid PoGo (thenewinstant.com). The PoGo, which stands for Polaroid-on-the-Go, is an inkless printer that churns out 2×3-inch photos sent to it via Bluetooth devices like cellphones or from plugged-in digital cameras. It uses technology created by ZINK (Zero Ink) Imaging Inc. to activate paper-embedded dye crystals, creating a new kind of photo magic. The PoGo will be in stores on July 6.

Cool Factor

This device’s ZINK Technology gives it a cool factor that will leave friends scratching their heads over how such a small device can print without ink (technical details about the 100 billion heat-activated dye crystals on each sheet of paper can be found at zink.com/technology). Photos that I printed from a 10-megapixel digital camera looked sharp and colorful. And some people may use this Polaroid gadget as a solution for freeing images that would otherwise likely remain stuck in a mobile device’s memory.

But four major problems with the PoGo make it a no-go: It isn’t quite small and light enough to be truly portable; its battery life is poor; its prints are half the size of normal photos; and image quality when printing from mobile devices is unimpressive — though this can be attributed to the low-resolution images taken with and stored on these devices rather than the printer itself. For roughly the same price, you could buy a photo printer that produces better quality 4×6-inch or larger prints.

The PoGo works only with ZINK Photo Paper, which costs between 30 cents and 40 cents a page, depending on whether you buy a 10-sheet pack for $3.99 or a 30-sheet pack for $9.99. (Later this year, a 100-sheet pack of ZINK photo paper will be available for $29.99.) The PoGo comes with 10 pieces of this paper, which is coated with a waterproof, tear-proof, smudge-proof, semi-gloss finish. You can peel the backs of these 2×3 prints to stick them to things, though not in the same way Post-its can be stuck and removed (they leave a gooey film — I learned the hard way).

A Device With Weight

Surprisingly, Polaroid is touting the PoGo’s portability; it arrived in a custom-made jeans pocket to demonstrate the device’s pocket-sized shape. But at over 8 ounces, this thing was heavier and measured larger than Apple’s (AAPL) biggest 160-gigabyte iPod Classic. It even weighed more than a bulky point-and-shoot Kodak (EK) camera I recently tested, discouraging me from bringing it along when I went out.

A chart on polaroid.com/pogo/us/comp.html tells whether or not your mobile device is Bluetooth-compatible with the PoGo. Two out of the three devices that I tried worked: A new Motorola (MOT) Z6C and Research in Motion’s (RIMM) BlackBerry Curve were compatible, though an almost-two-year-old Motorola Razr V3 wasn’t.

Each mobile device needed only one initial “pairing,” or setup, with the PoGo before it sent photos. The device used a simple method of sending photos via Bluetooth that generally involved selecting a photo and telling the mobile device to send it to the PoGo. It usually took a few seconds for the send to go through.

The PoGo doesn’t have a display to tell users when images are received, when to load more paper or if the battery is running low. Instead, it uses two indicator lights that glow or pulse in green, orange or red colors. Each light means something different, such as whether or not the PoGo is ready to print or if it has a paper jam, but I usually had to refer to the user’s manual to figure out what each light meant.

Quiet Printer

The PoGo is rather quiet while printing, making a soft whirring sound as its thermal print head turns on and zaps dye crystals, which are embedded in the ZINK photo paper. These small pieces of paper are stored in and printed from a holding space inside the device, which saves users from opening a tray and loading paper before each print-out. However, the PoGo can hold a maximum of only 10 sheets at once. Some images printed in 45 seconds and a few took about twice that long, but most were done in about one minute — counting from when I pressed Send on a mobile device to when the print finished.

I hooked a Sony (SNE) Cyber-shot DSC-W170 to the PoGo via a USB cord and used the camera’s built-in PictBridge technology to print from the camera, following directions on the camera’s display screen. I even printed four of the same photo at once after adjusting the quantity category in a menu, though this seemed to slow the printing process a bit.

While prints from my grandmother’s Polaroid camera couldn’t be touched until about a minute after printing, the small PoGo prints come out dry to the touch. I held one under the kitchen faucet to test its waterproof claim, and the colors held up without running. These prints are borderless, which looks good but seems like the only sensible option with such small paper. Images from the digital camera looked dramatically better than those taken by mobile devices’ 1.3-megapixel or two-megapixel cameras.

Short Battery Life

The PoGo’s battery life wore out quickly, especially for a device that is advertised as portable. In one test, after I unplugged my fully charged PoGo and used it for about 40 minutes to print 16 photos — half from a Bluetooth-connected cellphone and the other half from a USB-connected digital camera — its battery indicator glowed a steady orange, meaning the PoGo was running low on power. This is about right, considering Polaroid claims that a fully charged battery will last for 15 prints. (It takes about 2.5 hours to fully charge the PoGo.)

I really liked the quality of the photos that PoGo printed from my digital camera — in fact, I’m planning to enclose a few small PoGo photos in cards that I send to friends and family members. But the PoGo’s awkward size, bad battery life and small prints make it a tough sell. I’m afraid the PoGo falls short in too many categories to be a practical gadget. Teens might like this device for printing photos from their cellphones that they can stick on lockers or books. And who knows — maybe a grandmother somewhere will buy one of these gadgets to create a little Polaroid magic for her grandchild.

Wouldn’t it be great if, after attending an event — like a wedding — at which friends and family took digital photos and videos, everyone could contribute to the same online album? It would be even better if everyone could access the album through a simple email invitation instead of having to create yet another log-in profile.

The once-frustrating process of sharing digital photos and videos has noticeably improved over the past year, thanks to seamless Web-based programs that work like desktop applications. But many of these sites give all the power to whoever created the album, leaving invited guests to simply look at photos or add comments.

Shwup by muvee Technologies gives friends a common album in which to share digital photos and videos.

This week I tested shwup (www.shwup.com), a free Web-based application that’s available starting Wednesday from muvee Technologies and works as described above with only a few pitfalls. The concept is simple: Anyone who signs up for a shwup account can create an album filled with digital photos and videos, and this album can be shared with anyone else via email whether they have a shwup account or not. Recipients of these email invitations can click on an embedded link to view and add content to the album. Or users can completely skip visiting the site and instantly upload content by replying to the email invitation with attached photos and videos.

Muvee Technologies is best known for selling software that automatically creates short movies, or muvees, by blending digital videos and photos with music and transitions. Muvee’s namesake technology is a part of the free shwup site; a few muvees are automatically generated in each of the albums and everyone who is invited to the album can create muvees using its content. But shwup’s main focus is making sharing easier for everyone. It differs from most of the company’s software programs in that it’s free and completely Web-based.

A shwup album takes just a few minutes to set up and even less time to share. It works on Microsoft’s (MSFT) Internet Explorer and Mozilla’s Firefox 2.0 and 3.0 browsers but won’t work on Apple’s (AAPL) Safari until the fall. Shwup is available Wednesday but is still technically in its beta, or testing, phase, and I ran into a few kinks. I had trouble getting its useful reply-to-email uploading capability to work when two friends and I tried to upload content to my album using attachments in email replies. My friends had to visit the site to upload content. Muvee couldn’t figure out what went wrong when I asked the company about it.

I did, however, add content to someone else’s album using the reply-to-email method, uploading a digital photo in seconds. And in another instance I received a shwup email invitation on my BlackBerry and replied to it with an attached photo, which — in seconds — sent that photo from my BlackBerry to the specified shwup album.

Shwup automatically makes muvees, or short movies with music and transitions, using album content.

A glaring omission from shwup is the ability to view photos in full-screen view, a feature that most photo-sharing programs offer in slideshow mode. A friend of mine said he would use shwup over other photo-sharing Web sites that require user names and passwords if only it had full-screen photos. Muvee recognizes this as one of shwup’s biggest issues and says it will add this feature in August.

I uploaded over 60 high-resolution digital photos into my first shwup album, noting that the only limitation on files is that no individual file can be larger than 100 megabytes. These images can come from your computer, Flickr, Facebook or any Web site. Out of curiosity, I plugged www.cnn.com into the Web site entry box and shwup automatically grabbed images from the site that were available for me to use. I checked two of the images and they were added to my album in seconds.

Shwup automatically made and added three muvees to my album, using my photos put to music it chooses with dramatically timed transitions. These short clips looked really well-done, and were labeled as “sample muvees” so as not to be confused with my content. I followed a few simple steps to create a muvee of my own for the album by dragging photos into a tray, choosing from seven different layout styles and a handful of stock music licensed by shwup.

An option lets you upload your own music to play with your muvee, which I did. Seconds later, my homemade muvee played with transitions that were perfectly timed to the beats of a Fountains of Wayne song. After filling an album with digital photos, videos and muvees that I made, I invited friends to my album using emails generated from shwup.com. Within each album, a clear list of whoever was invited to the album can be seen on the top right side of the page. If someone hasn’t shared content yet, he or she can be “poked” by anyone invited to the album, sending them yet another email invitation.

Everyone invited to an album receives notifications from shwup whenever someone contributed content to the album and everyone can change the layout of the album to one of three settings: Grid, Simple or Mosaic. Moving my cursor over an album’s images showed data about each file including who contributed the photo or video, when it was captured and how many comments it had received in the album. (Comments are readable after clicking on an image to see a bigger version of it.)

Digital videos are labeled with small Play icons to distinguish them from digital still images. But a friend who uploaded a video to my album pointed out that the still image representing his video was a gray square rather than a still of the first scene as it did with the other videos — perhaps because this is where the camera was focused at the start of the video. Without an image to illustrate what the video was, it wasn’t as appealing as the other videos and images. Muvee explained that the ability to select a still image to represent a video was available in its pay software, but not yet in shwup, though the company plans to add this to shwup in the future.

Another hitch: If you invite someone to your album and then add something to the album you’d rather they not see, you can’t un-invite the person. Muvee says it plans to add the ability to un-invite members in July. Individual contributors have the ability to delete or “unshare” the content that they added to an album, while album creators can unshare and delete all pictures or entire albums. Album creators also are given the authority to merge albums.

Along with shwup, muvee also announces a new version of its downloadable pay software Wednesday: muvee Reveal. This $100 software has much more detailed features that specifically tweak your videos to become extra personalized.

When it works, shwup serves as a neat, artistic way to share photos quickly. Friends and family will be relieved that it doesn’t require any forgettable usernames and passwords, and the email-uploading tool will make anyone who knows how to attach something to an email feel like he or she can contribute to a photo-sharing Web site without a second thought. After shwup adds its full-screen photo-viewing option and clears up the glitches of its email-uploading feature, I’ll be using shwup for many group events to come.

When Pure Digital Technologies Inc. introduced its Flip point-and-shoot camcorder a year ago, it dramatically simplified video recording. The Flip measured the size of a small digital still camera, cost less than $150 and its videos could be emailed in one quick process. Consumers gobbled up the tiny, nonintimidating device.

But to the style-conscious set, the Flip looked like a clunky Fisher-Price toy — especially when compared with a sleek, new iPod or more-sophisticated digital cameras — and was too thick to comfortably slip into a pocket. Last fall, Pure Digital introduced an enhanced version: the Flip Video Ultra, but its biggest aesthetic difference was new orange, pink and green colors.

Today, the company will begin sales of its $180 Flip Video Mino (pronounced “minnow”), the hippest offering yet from Pure Digital. This 60-minute Flip includes many firsts for the company: rechargeable batteries; touch-sensitive buttons rather than old-school, push-down buttons; and a thinner build that measures 40% smaller, overall. The Flip Mino is also the first one in the family to enable publishing to MySpace (NWS); prior software limited Web-site sharing to YouTube (GOOG) and AOL (TWX) Video.

I’ve been using a glossy, black Flip Mino (it also comes in white) for the past two weeks and it looks much cooler than older models. Its newly positioned USB adapter pops up from the top of the camera like something from a Swiss Army Knife. The Mino offers features such as the ability to lock the delete button, so no one accidentally deletes your videos, and mute all camera sounds, so as to record silently during quiet moments like wedding ceremonies or speeches.

I brought it along with me almost everywhere I went because of its small size and light weight, even fitting it into a thin clutch purse with a cellphone and BlackBerry (RIMM). I used the Mino in various situations ranging from bright, scenic outdoor settings to indoors while eating dinner in a candle-lit restaurant. Overall, I was pleased with the sound and picture quality of the Mino, and I found its built-in software, which automatically starts when the camera plugs into your Mac (AAPL) or Windows (MSFT) PC, to be a pleasure to use.

Today, Pure Digital Technologies introduced its $180 Flip Video Mino, a thinner, more stylish version of its point-and-shoot camcorder.

It took just a few minutes to trim excess footage from my videos before saving them to my computer or sharing them with friends and family. Another way to share videos from the Flip Mino is via Pure Digital’s server, which sends emails with embedded video links, saving upload and download time on both ends. Though I didn’t publish any of my videos on a public Web site, AOL, MySpace and YouTube were just one step away.

The Flip Mino’s touch buttons, while stylish, were difficult to use at first. I missed the tactile feel of physical buttons as I tried to hold this small video camera and press the zoom buttons using just one hand. The new, touch-sensitive buttons weren’t as satisfying and stable to use, and I pressed them accidentally more than a few times. For instance, the Zoom Out button is directly below Record, making it easy to mistakenly touch it. After about a week of using the Mino, I grew more accustomed to using these new touch buttons, but it shouldn’t take so long to make the adjustment.

Just looking at the Flip Mino’s fresh new exterior makes it hard not to think about the things that this redesigned camcorder is still lacking, like a larger viewing screen (the Mino screen is 1.5 inches, no larger than that of the Flip Ultra), high definition video and wireless sharing capability. These features would likely raise the price and/or tax the battery, and many users of the Flip flock to it for its low price and simplicity. Still, Pure Digital says that it will offer HD video and a larger screen on a product within a year, and is looking into features that might include wireless transferring.

I grew fond of the Mino’s rechargeable battery. Whenever I plugged this gadget into my computer to transfer videos, my Mino charged up via USB without me having to think about it. A full charge lasts four hours and recharging a dead battery takes about three hours.

Pure Digital says that the sound quality and lighting are improved in this model. Like previous models, this Flip records in 640×480 pixels at 30 frames per second.

The Mino didn’t have a problem with lighting in most situations; indeed it did a nice job of capturing images of my family sitting around a table in a restaurant with little more than candlelight to brighten the picture. It doesn’t use a flash or a built-in light, but instead uses automatic sensors to adjust to various levels of light.

This svelte camcorder seemed to handle noise more evenly than I remembered in prior Flip models. It didn’t make my voice sound unbearably louder than everyone else’s, even though I was closest to the camera’s microphone, yet it managed to detect voices across the room. I did have some trouble on a windy day: While recording a quick video of a golf course in San Diego, wind audibly muffled my voice during a few moments in the video.

Along with the delete-lock and sounds-off settings, this Mino has a few other tricks up its sleeve. Each of the touch-sensitive buttons is designed to glow only when usable, so as to better help people who might not know which buttons to press while using this camcorder. For example, only the zoom buttons glow while recording since the other buttons (volume, play/pause and delete) can’t function in this setting.

Shortcuts built into each button provide more functions: Holding the play/pause button down will set the playback mode to play all videos on the Mino; holding the seek ahead or seek back buttons while watching a video will fast-forward by seconds within that video; pressing the record button as the camera starts up opens up the settings menu.

In conjunction with the Flip Mino’s introduction Wednesday, prices of the former Flip Ultra model will drop to $150 for the 60-minute model. The Flip Ultra 30-minute model will be phased out, as will the Flip Classic, which will cost $130 for a 60-minute unit.

Though the Flip Mino’s touch-sensitive buttons look great, they aren’t as functional as they needed to be. But if you really want a sleek, hip-looking gadget, you’ll learn to adjust to these new buttons. No matter which Flip you choose, Pure Digital’s software changes the way people capture and share videos, and that’s a great thing.

Nintendo’s Wii made its mark as the fun system that got gamers and non-gamers alike off their couches to play tennis and golf with motion-sensing controllers. On Monday, the company will introduce an accessory that encourages users to take exercising with the Wii even more seriously: Wii Fit and the Wii Balance Board.

The Wii Balance Board measures shifting weight.

For the past eight days, I’ve been stretching, crunching, yoga-posing and even running using this $90 package from Nintendo (NTDOY.PK). Wii Fit is the title of the disc that comes with the Wii Balance Board, a sturdy platform on which you perform your routines. The two are used together for various types of yoga, strength training, aerobics and balance games, which involve the Wii game system’s “Miis” — on-screen representations of yourself — that interact with trainers and other virtual characters. Sensors in the Balance Board detect a user’s weight, body mass index, balancing skills and positioning during activities, and the Wii Fit program keeps track of this information, providing tips on technique or weight loss. Wii Fit and the Balance Board must be used with the original Wii system, which costs $250.

I’ve grown fond of using Wii Fit and the Balance Board because it holds me accountable for my weight and balance skills. I learned fitness and health tips from a small, animated image of the Balance Board that jumped around on-screen — such as the fact that people who cross their legs while sitting are more likely to have back problems. And after a few days of using the system, I could feel a difference in my muscles.

For those used to 30-to-40-minute workout sessions, the Wii Fit programs may seem lightweight, since activities last for only about three to five minutes each. To unlock longer activities or additional strength-training repetitions, you must first do them a handful of times in their short versions, which can be frustrating. Nintendo says this is designed so that average users don’t feel intimidated, but I felt like some of the activities ended just as I was getting into them. Almost all activities involve actually standing on or touching the board.

Motivation is a key element in the Wii Fit programs. An on-screen graph tracked my progress, and I “stamped” each calendar day to show that I had exercised. Each minute of activity added a point to my Fit Bank, and enough points unlocked new activities; Wii Fit includes over 40 altogether. On-screen instructors demonstrated and joined me during yoga and strength-training exercises, congratulating me when I held my balance or noting that I stopped mid-exercise.

A daily body test measured my weight and body mass index against those from previous days and challenged me to two short balance tests, which changed daily. After, I was told my Wii Fit Age, a number reached using my actual age, BMI and performance on the balance tests. On good days this number was a couple of years below my real age, but it drifted upward when I was given harder tests, sometimes reaching 13 years older than my actual age.

Top: Wii Fit charts fitness progress over time, including body mass index and weight. Yoga (middle) and balance games like Ski Slalom (bottom) mirror board movements.

More than one person can use the system and profiles can be password protected. Friends can use the Balance Board under someone else’s profile; the system notices weight changes and confirms that it’s alright to continue.

The Balance Board measures roughly the size of a step used in step aerobics classes, and uses the same technology that gauges the weight of airplanes. These sensors expand and contract when someone stands on the board, measuring weight, and where and how that weight is shifting on the board. This works out of the box with four included AA batteries. Its power button can be nudged on with a foot, turning off automatically after five minutes of non-use.

I started with basic yoga, attempting the half-moon pose. I opted for a male instructor who told me that this position helped improve posture and digestion. He briefly demonstrated the position, and we got started on the actual session, which lasted two minutes. A large, on-screen circle that expanded and contracted illustrated when I should inhale and exhale as I held positions. I tried the Warrior, Tree and Sun Salutation positions throughout the week.

In the strength-training section of the program, I liked the Single-Leg Stretch exercise, which involved standing on the Balance Board on one leg and holding the other leg off the ground, bent up toward my chest. I slowly extended this bent leg out and in, while moving my arms and trying to maintain my center of balance. This exercise started at six repetitions, but increased to 10 reps as I improved; 20 reps are the maximum.

I tried the Torso Twists and Rowing Squats, but had a lot of trouble with Push Ups and Side Planks (modified push-ups), because I’m not good at push-ups. To my surprise, my trainer didn’t notice when I couldn’t finish the session. I got my best score on that exercise, clearly a flaw in the system.

During yoga and strength-training exercises, an on-screen red dot marked where my center of balance was detected, and I was encouraged to try to keep that dot within a highlighted area. After the exercise, a diagram showed where my weight had shifted, and I earned better rankings when I distributed weight evenly.

Aerobics were more fun, including hula hooping. I rotated my hips and I leaned forward so that my on-screen cartoon self could catch hoops thrown over my head by other characters. The Balance Board tracked the number of times I rotated my waist around in a circle. One aerobics activity that didn’t use the board was Basic Run, which requires users to put the Wii remote in a pocket or hold it while running in place for time intervals measuring three, five or 10 minutes depending on the pace. This mode is designed so users can either watch other runners on-screen or tune into television while running as Wii Fit tracks your progress. An aerobics activity called Basic Step was like Dance Dance Revolution: on-screen footprints showed where and how to step next — on and off the board.

Balance Games were fun — but hard. I tried a bunch, including Soccer Heading (where you pretend you’re the goalie), Ski Slalom and Tightrope Walk, and was surprised by the sensitivity of the Balance Board. But the more I played, the better I became at controlling my balance.

I brought the Wii and Balance Board with me to my parents’ house last weekend, but most people will do best to keep this board in one place since it weighs 10 pounds.

When I stepped onto the Balance Board at my parents’ house in a room with wall-to-wall carpeting, the system thought I had lost 13.4 pounds since the day before. I stepped off and tried this measurement again a few minutes later, but was told I lost another 4.6 pounds. However, when I returned to my own home with the board on an area rug on hardwood flooring, the system showed I “gained” 16.1 pounds. My weight at my own house was on the mark.

Some of my relatives jokingly saw this instant weight loss as a reason to buy a Balance Board, but this made me question the system’s accuracy.

Nintendo solved the mystery: The carpeting in my parents’ house, which I mistakenly thought was similar to the area rug in my house, must have been touching the bottom of the board, therefore transferring my weight onto the carpet and away from the board. Four circular “feet” come with the Balance Board to elevate it, solving the problem.

When the Wii Fit system thought I lost or gained a lot of weight in one day, it was concerned and offered tips for healthier fitness. In the case of the supposed weight gain, I was asked to think about why I might have gained weight, then had to select an answer from a list of reasons why, including Late Dinners, Night Snacking and Not Exercising. The system gave health tips related to the reasons.

Users’ outside exercise can be accounted for in the system. I added the time I spend playing tennis each week and this information plugged into a graph to illustrate fitness activity over time.

The idea of having a virtual trainer and a way to set weight-loss goals while tracking progress could be truly valuable for people in need of motivation without the expense and/or hassle of going to a gym. If you’re looking for a fun way to get in shape, the Balance Board will do the trick. Like the Wii, its activities encourage all sorts of people to use it, marking yet another smart move from Nintendo.

If there’s a skill or process you want to learn or know more about, chances are there’s an online video for it. These days you can find a video that will teach you to cook, survive college, build your own headphones or even become a better kisser.

This week, I took a look at just a few Web sites that make finding these videos easy, including Howcast Media Inc.’s Howcast.com, WonderHowTo.com from WonderHowTo Inc. and eHow Inc.’s eHow.com. Howcast.com, which launched in February, encourages users to make and share good-quality, entertaining videos by providing tools on its site, and has about 5,000 videos so far. WonderHowTo.com, launched in January, used a different strategy by aggregating over 110,000 videos from various sources — including Howcast, YouTube and Scripps Networks (SSP) — rather than publishing its own content. EHow, a site that started in 1999 with text-only content, contains over 100,000 instructional articles submitted by its users or eHow editors, and has a small catalog of videos.

Howcast videos can be seen in full-screen mode using a player that illustrates step-by-step text instructions beside video screens.

After testing each of these sites, I found that my favorite how-to videos had steps that were clearly labeled and numbered and the ability to fast forward to or play back specific parts in the video — tools that Howcast included in almost all of its videos. At least some of the videos on the three sites simply illustrate things you could likely figure out how to do without watching a video, such as “How to Make Green Beer.” (Add food coloring.) Howcast.com and WonderHowTo both require users to sign in, which confirms their date of birth, before looking at what they consider “mature” content.

These three free sites are advertisement-supported, and Howcast’s ads run alongside videos. WonderHowTo.com runs ads at the top and side of its own site, on which it will play certain videos. But because videos on WonderHowTo come from other sources, those other sites can show video-embedded ads according to their rules. EHow’s videos run pop-up text advertisements displaying names and links of other related (and sometimes unrelated) Web sites. But I couldn’t get the pop-up ads to stay closed.

Overall, I preferred the look of Howcast’s site and its well-organized videos. But its content paled in comparison to WonderHowTo’s 110,000 videos and even eHow’s 100,000 instructional articles. WonderHowTo.com does a nice job of gathering content from across the Web, though the inconsistencies of other sites (including advertisements, layout and video player) were a bit frustrating. EHow’s articles were useful, as were its few videos, but I couldn’t get over the site’s unyielding video pop-up ads.

Howcast.com’s content was informative with an amusing edge, including a video titled “How to Tell If Your Boyfriend’s A Psycho.” (If he calls 50 times a day, for example.) Other videos on the site are more serious, like “How to Make Sushi” by an executive sushi chef in New York City.

The founders of Howcast Media formerly worked in Google’s (GOOG) video department, including during the acquisition of YouTube. All of Howcast’s content comes from one of four sources: written and produced by Howcast in its studios; emerging filmmakers who apply and are accepted into the Howcast Directors Program to receive $50 a video and 50% of the advertising revenue generated from videos that generate over 40,000 views on the site; content partners like Popular Science; and Howcast users’ personal how-to videos.

In order to make it easier for average users to upload better-looking videos, Howcast provides an Upload and Enhance tool that simply and quickly adds professional-looking graphics and printable steps to go along with how-to videos. This formula makes videos more enjoyable to watch.

Videos made in the Howcast Studios include accompanying music, good narratives and actors who add humor to an otherwise humdrum how-to. Among its helpful features is a video player that has smart blue markers to show where facts are sprinkled throughout the video and green markers to illustrate where tips appear. For example, the fact at the end of a video for beginner guitarists called “How to Play a Basic Bar Chord” is “The late Kurt Cobain claimed he was trying to rip off the Pixies when he wrote ‘Smells Like Teen Spirit. ‘” In full-screen view, users can zoom in on any part of a video, and written-out steps and thumbnail stills of the scene appear to the right of the screen.

Howcast tries to run ads alongside videos that relate to the content. A video titled “How To Clean Your Dog’s Teeth” has an ad for PetSmart (PETM) Stores running on its page.

WonderHowTo.com was developed by a former television executive with the intention of using the site to produce its own video, like Howcast.com. Instead, WonderHowTo.com opted to tap the vast selection of how-to videos already available on the Web.

A Browse button pulls down 35 categories from which users can sort content, including Spirituality, Dating & Relationships and Fitness. In the Fashion subcategory under Beauty & Style, I found 290 videos including one on “How to Tie a Windsor Knot” and another titled “How to Turn Old Underpants Into a Bra” — neither of which I’ll be using anytime soon. Other categories include Clip of the Day, Recommendations (for users who are logged in) and Fresh, where new videos are listed. Users can grade videos to help others tell which they think are the best, and a Top Grade category compiles the top-ranked videos.

WonderHowTo’s content comes from over 700 sites, according to the company. I used the site to find a video on YouTube about how to do a front-flip, clips on VideoJug.com that provided terrific tennis tips from a coach, and a video from EasyBarTricks.com about how to stick a beer bottle to a wall without glue or gum. (Hint: You’ll need a corner and a wall you don’t mind marking up.) WonderHowTo made it easier to find these videos than by performing a general search on the Web.

I submitted a non-how-to video to this site by simply entering a URL, without logging in. I never found the video I submitted on the site; WonderHowTo explained that it screens all videos prior to posting them, so it must have found my video.

EHow.com uses its database of articles to encourage people to watch videos, when they’re relevant. This site uses calm, pastel colors to give a relaxed feeling — especially compared with WonderHowTo, where banner ads surround the page. EHow’s 26 categories include Parenting, Parties & Entertaining and Weddings. Twelve subcategories within Weddings led to 23 articles about Bridal Party Responsibilities — a popular topic was “How To Deal With a Bridezilla.” Related videos, such as “How To Get Rid of Wedding Day Jitters,” ran along the right of the page.

Videos can also be found on eHow within a marked tab at the top of the page. But unlike the articles on eHow, these videos weren’t well organized or as easily searchable. I watched one of eHow’s Featured Videos called “How to Know if Your Toe Is Broken,” but after closing a pop-up ad for UPS (UPS) during Step One of the video, another ad popped up during Step Five. Neither ad had anything to do with broken toes.

But the eHow videos were professional-looking and included quite a few tips that I didn’t know. That broken toe video was submitted by the eHow Health Editor, and a link at the top of the page led me to hundreds of other health-related articles. I found another video on “How To Remove Wallpaper,” which was posted by the Home & Garden Editor and included a list of things I would need to proceed, along with numbered steps.

It isn’t always easy to learn from the information you find online, and how-to videos can be a big help — especially when they’re well-made and easy to find using one of these sites. Howcast.com has well-presented content that was enjoyable to watch, but WonderHowTo.com offers a better variety of instructional videos.

My Dad will be proud to read that I’ve spent much of the past week studying my finances and figuring out my budget. But I’m willing to bet (figuratively since betting isn’t in my new budget) he’ll be surprised to learn that I did this in no time using a Web-based program that didn’t cost me a dime.

This week, I tested a free Web site called Mint.com that serves as a Web home base for account information from credit cards, credit unions and bank accounts. The site securely and automatically logs into those accounts, fetches the latest data and presents the information in easy-to-read and useful ways.

Mint.com lets users track their expenses via pie charts (top) and offers alternative savings options (bottom).

Mint hopes to help users get a better handle on where their money is going, how much is in each account, and what can be done to budget that money more efficiently. It sends automatic alerts about account data or when you exceed your budget. It can even translate a bank’s often odd rendering of merchants’ names into plain-English versions of your financial transactions.

Starting May 6, the site will let users add investments, such as individual retirement accounts and 401(k) plans, to their accounts, though Mint isn’t designed for serious investors. Today, readers can get sneak peak access to this Investments feature via www.mint.com/wsj. In June, Mint will add auto loans, student loans and mortgages.

Mint won’t work offline because it’s completely Web-based, and can’t be used to pay bills or move any money around, meaning people will still need to visit separate sites for bill payments and money transfers.

Talk of money-related software programs often brings to mind the old reliables: Intuit Inc.’s (INTU) Quicken and Microsoft (MSFT) Money. But some of these programs can cost close to $100 and require intense bookkeeping. Stripped-down versions of these products are available, but these still include fees. Geezeo.com is a Web service that’s more comparable to Mint.com, but it incorporates social-networking tools like introducing users with like interests.

Mint was created for 20-somethings like me who want to pay more attention to their finances but aren’t interested in taking hours each week to do so. This Web site worked ideally for me, and its clean interface integrates Web 2.0 features in a way that makes it a pleasure to use. I think it will appeal to a broad range of people who want to feel more in control of their money, but don’t want to spend a lot of time updating their information.

I set up my information on Mint in minutes, not hours, and used it to track five accounts. In seconds, Mint used data from my accounts to automatically generate colorful pie charts that illustrated where my money was spent — and most expenses were accurately labeled. I was pleased to find my local bank in a list of Mint-supported companies. And the site even encouraged me to look at my 401(k)’s progress online for the first time in a while because I didn’t need to dig into an out-of-the-way, unfamiliar Web site.

Security is important for a site like Mint.com, so it teamed up with online banking-service provider Yodlee to make secure connections to banks. This involves using encryption that the company claims is the same as what banks use. Mint also says that because it requires nothing more than an email address, password and ZIP Code from each person, registration is anonymous. And the company claims that it never sees or stores password information, nor does it ever see account numbers.

When setting up an account, Mint acknowledges nicknames for companies, like Amex for American Express (AXP), making it easy to find specific banks and credit-card companies. If you’d like to sign up on Mint, but don’t already have online accounts set up, Mint will give step-by-step directions on how to do this — whether via a company’s site or by phone.

The site suggests alternative companies that will save you more money than those you’re currently using. Some, but not all, of these companies are sponsors of the site. After entering my savings-account information, I learned about a high-yield savings account that would potentially allow me to earn hundreds more in interest each year. Some of these suggested alternatives were familiar, while others — like Bank of the Internet USA — weren’t.

I found Mint’s automatic alerts to be especially helpful. Each alert can be personalized to notify you via email or an SMS message on your mobile phone when something happens in an account. Account summaries, for example, can be sent via email and text message every Friday, the first of every month or never. Alerts can be adjusted to tell people that their credit-card bill is due within a certain number of days; if a pre-set budget is exceeded; or if a bank charges extra fees.

Mint’s new Investments section showed me details about two investments. A handy graph showed the status of my account earnings and compared them with the Dow Jones Industrial Average, Nasdaq and the S&P 500. Individual stocks can be added into your account, though I could see only the balance of a trust holding one of my stocks.

In the Trends section, I learned what my most frequent expenditures were, as well as the total amount of money spent per month, which was interesting to see since I don’t usually add up all of my expenses. Trends can show you how your spending stacks up with everyone else — that is, people in the U.S. who use Mint. My account showed I ate at a Chipotle (CMG) chain restaurant once in February and once in April, spending the exact amount each time. (I like their barbacoa fajita burrito.) But I spent about $4 to $5 less than the average Chipotle customer.

If certain expenses are mislabeled, they can easily be renamed and reassigned to different categories. Pie charts and graphs can be altered with one mouse click to become more or less specific, and budgets can be set after looking at spending history on an easy-to-understand bar graph.

Digital conveniences like online bill payments and Web transactions can lead to people putting less thought into their finances. But the value of knowing specifically where money is and how it is spent is a tool that will likely encourage better financial planning and habits. I only wish Mint had a way to incorporate online bill payments so I could do all of my financial work in one place on this site. Otherwise, Mint is a real boon to people who want to tell their dads that they’re on top of their finances — and mean it.

Most digital cameras have more settings than the average person knows what to do with — from common adjustments for nighttime and face shots to obscure settings for sports, fireworks and snow scenes.

When the moment comes to take the perfect picture of a snowy mountaintop, Fourth of July fireworks or soccer goal in midkick, most people forget about these features or don’t know how to use them. And while many digital cameras can now detect faces and make sure they are in focus, they can’t tell whether that face is smiling or not. The results aren’t bad, but they could be much better.

Sony’s Cyber-shot DSC-W170 uses Smile Shutter Mode to snap pictures when a subject smiles.

This week, I tested three new digital cameras that claim to do the thinking for you. Some digitally analyze the scene you’re about to capture, automatically choosing the setting that would take the best picture. Others can detect when a subject is smiling so as to automatically know when to snap the photo. One camera even attempts to digitally alter frowning faces into smiles, with amusing results.

I tried out Sony’s $300 Cyber-shot DSC-W170, Kodak’s $250 EasyShare Z1085 IS and Olympus’s $200 FE-340. Only the Sony (SNE) includes all three of the aforementioned features; the Kodak (EK) has scene detection, and the Olympus (OCPNF.PK) camera has built-in smile detection. I found the automatic scene detection offered in the Sony and Kodak cameras to be the most useful feature for everyday photos. It improved my photos and didn’t require any extra adjustments. I handed the cameras to other people to take pictures, without having to change any settings.

The automatic smile detection offered in the Sony and Olympus cameras was fun to use and could be especially helpful for families whose young kids never seem to smile at the right moment. But it didn’t work consistently and had trouble detecting my bearded boss’s smile and even that of a beard-free colleague.

I found Sony’s frown-fixing tool, which is called Happy Face Retouch, to be rather unusual. It took already captured images of my friends’ faces and turned their frowns or ambivalent looks into smiles, but didn’t adjust the subjects’ eyes. Though this was good for laughs, the eerie-looking grins pasted on faces reminded me of painted-on clowns’ mouths. And some attempts to retouch a face couldn’t detect the face to alter it. But a handful of the Happy Face Retouches looked somewhat natural.

Similar Specs

These cameras boast many similar specifications. All three use 5x optical zoom lenses, and the Sony Cyber-shot DSC-W170 and Kodak EasyShare Z1085 IS each have 10.1 and 10 megapixel image sensors while the least expensive Olympus FE-340 has 8 megapixels. The Sony and Olympus both have generous 2.7-inch viewing screens and almost identically sleek builds, though the Sony is the only one of these three cameras to have an optical viewfinder.

The Kodak’s viewing screen is slightly smaller than the other two digital cameras, measuring 2.5 inches, but its build isn’t nearly as compact as the others. It reminded me more of small, high-end SLR camera, with its comfortably large hand grip, a settings knob on the top edge of the camera, and a protruding zoom lens.

Sony’s Happy Face Retouch feature digitally changes facial expressions into smiles, but all it did was make me look unnatural and awkward.

Kodak’s EasyShare Z1085 IS takes Secure Digital (SD) memory cards, which are more common than the Memory Stick and xD cards that work in the Sony and Olympus cameras, respectively.

The Kodak and Sony digital cameras have different names for their automatic scene-detection features. By default, the Kodak camera works in Smart Capture Mode, which includes intelligent scene detection, capture control and image processing. I focused on the camera’s scene detection, which automatically determines whether the photo should be taken in Macro, Text (for shots of text in a book, for example), Face, Landscape or Night settings.

Icon on the Screen

I snapped pictures around Washington, D.C., noting a tiny icon on the camera’s screen that indicated which of the five scene modes was being used to capture the photo. A flower icon indicating Macro appeared on my screen when I stooped to get a close-up shot of a tulip, and an icon of a dark sky and stars showed on the screen when I took photos at night. The camera’s flash, focus and exposure changed according to the type of photo.

The Sony camera uses what it calls Intelligent Scene Recognition to decide which settings should go along with certain photos. Like the Kodak, icons on the Sony’s screen indicated the scene settings that were automatically deemed appropriate, including Backlight, Backlight Portrait, Twilight, Twilight Portrait and Twilight Using a Tripod.

The Sony’s Intelligent Scene Recognition isn’t on by default like Kodak’s feature. Instead, it must be turned on from within a menu, but once on, it stays on until you turn it off. ISR can be used in either Auto or Advanced mode; Auto takes a single photo with automatically determined settings, while Advanced takes two shots — one with manual settings you can choose and another shot immediately following the first with automatic settings according to what the camera thinks is best.

I experienced surprising results with the Sony Cyber-shot DSC-W170 and Olympus FE-340 while testing their automatic smile-detecting functions. My friends thought I was joking when I told them the camera would take their picture only if they were smiling. When the flash went off multiple times as they kept smiling, they were intrigued by this feature.

Sony’s version, which it calls Smile Shutter Mode, is easy to switch into by turning a dial on the camera to a smiley face. Once this setting is chosen and the camera’s shutter button is pressed, the Cyber-shot will search for smiles in its subjects, and will take photos whenever it detects a smile. Settings within this mode can be set to specifically detect an adult’s smile or a child’s smile, and the degree of smile can be set to low, medium or high; I kept things simple by leaving the smile detector on default settings.

Capturing Smiles

Olympus calls this feature Smile Shot, capturing three rapid shots in a row to make sure everyone’s smiling. The idea of taking three shots would be extra helpful with an indecisive baby, but most of my friends were able to hold their smiles, which produced three almost exactly identical shots each time someone smiled. Smile Shot is harder to get to in a pinch compared with the Sony: it’s buried in a list of 13 settings on the Olympus when the camera is set in Scene mode.

The Olympus seemed to be a bit slower than the Sony when it came to detecting smiles, but both had trouble with bearded men and even some folks without beards. And people felt silly standing around with a smile on their faces waiting for the camera to finally work. Closed-mouth, no-teeth smiles were harder for these cameras to detect, but not impossible. In group situations, the Olympus camera will focus on whoever’s face appears largest, which could mean the person closest to the camera, while the Sony takes a picture whenever anyone in the group smiles.

Putting a Happy Face On

If someone isn’t smiling, Sony’s Happy Face Retouch tool can come in handy, but don’t count on liking the results. In a group shot of five friends, two people who weren’t smiling put a bit of a damper on the whole shot. I used Happy Face Retouch, but it picked up on only one of the nonsmiling faces, turning a confused look into a smile that looked passable. But other results weren’t usable. A serious-looking shot of me deliberately not smiling looked freakishly unnatural after the touch-up, mostly because the rest of my face didn’t join the smile. I looked more like someone who had received too many Botox treatments.

Sony says that, in group shots, it can detect and change up to eight faces, but in my tests it usually changed only one. This retouching tool is also difficult to find: It took me 16 button presses to change each image into a smile — or what Sony calls a smile. A few times, Happy Face Retouch couldn’t identify a face in the photo, even when just one person stood in the frame.

These digital cameras took good photos, overall, and are fun to use because they take pressure off the photographer. I found the automatic scene-detection tools of the Kodak and Sony to be the most realistic and useful offerings, and I’m sure it won’t be long before automatic scene detection becomes as commonplace as an automatic flash.

It’s still too hard to share personal videos with friends and family in a truly satisfying manner. Huge video files take a long time to upload and download. And, even when you share clips via online streaming services that eliminate tedious downloads, you don’t get the fun experience of watching your videos together with others.

This week I tested SeeToo, a free service that lets you share videos in the same time that it takes to open and watch them on your own computer. Even better, you get to watch the video along with the people with whom you’re sharing it and type comments to each other in real time.

SeeToo works when one user selects a video to share with other people, who get an emailed hyperlink to SeeToo’s Web site, seetoo.com. After opening the link, these people join a SeeToo session during which everyone can watch the same video at the same time.

With SeeToo, you and your “buddy” can watch and chat about a video at the same time.

While the video is playing for the group, each viewer can pause, rewind and fast-forward the video. A space below the playback screen allows friends to send instant messages to one another during the session. There aren’t any limits to the size or type of video file that is shared, and other types of media — including music and photos — can also be shared on SeeToo without size restrictions.

SeeToo sounds too good to be true, and in many of my tests, it was. The service became available to the public in January in its beta, or test, stage. But I’ve used many other products in beta that were in better shape than SeeToo. And there is one major catch: Once a video-sharing session is over, the participants, other than the person sharing, can no longer access the video.

People who are invited to watch videos on the service can do so using any popular Web browser (Internet Explorer, Firefox or Safari) on Windows (MSFT) computers and Macs (AAPL). But the person actually supplying the video and initiating the sharing session can use only a Windows PC. The initiator also must download a browser plug-in, which seems old-fashioned in the world of Web-based applications. And sharing sessions time out after 15 minutes of inactivity on the initiator’s side, after which point the email link doesn’t work.

I was able to successfully initiate a SeeToo session using Firefox and Internet Explorer on an older Windows XP computer but had trouble with two computers running Windows Vista: Neither worked with SeeToo using Internet Explorer and only one worked using Firefox. SeeToo says this is due in part to Microsoft’s new Service Pack 1 for Vista, and the company claims it will have this problem fixed by today. I also had trouble with the sound.

The concept behind SeeToo is also somewhat limiting. Some people may not be able to watch a video exactly when someone else wants to watch it. Some might rather watch videos alone than with others. And typing out back-and-forth chats while videos are playing could be somewhat of a distraction from watching the video.

I tested SeeToo by sharing video with family and friends and watching video they shared. My sister and I got a kick out of watching video footage from a wedding I attended in October. I shot the video using an inexpensive, low-resolution Flip Video camera and the footage looked pretty good. But SeeToo’s site shares video on a rather small screen, and we both wished it were larger.

We sent instant messages to one another in a small space below the screen, making comments about the guests’ dance moves and the DJ’s choice of music. I used on-screen tools to pause the video when the camera passed by a friend whom I wanted my sister to see. To take a second look, she selected her screen’s Take Control button and rewound the footage to see my friend.

For the first two seconds of a video, users can see a small image in the top right corner of their screen that displays what the other people are seeing. SeeToo explained that this is a way of confirming one person is indeed seeing the same screen as another person.

I originally invited three people to watch the video with me. One friend I invited was at work, where his computer restricts him from watching videos. When he got home that night, the email hyperlink didn’t work — nor did it explain that the session had expired. Instead, it crashed his Firefox browser. I also invited my boss to watch the video with me, but he only saw my invitation two hours later when the session was over.

I didn’t even try to invite my parents to see the video because neither of them sit in front of a computer all day long and they wouldn’t have received my invitation in time to see the video.

In some ways, it was probably better that the other people I invited to watch the video weren’t able to see it, because the instant-message chat screen currently labels everyone as “buddy,” without distinguishing one person from another. SeeToo hopes to change this in future versions of the service by offering users a chance to register, thus receiving a specific nickname for chatting purposes. As of now, no one who uses SeeToo needs to enter any personal information such as a name or email address, which is a plus. SeeToo is also ad-free as of now, but the company plans to monetize parts of the service sometime this summer.

I also shared music and photos with friends using SeeToo, but this feature isn’t obvious; the site is primarily focused on sharing videos. Music playlists can’t currently be shared with friends, nor can photo slideshows be shared. Instead, individual songs or photos must be selected and shared within a session, one at a time.

SeeToo has high hopes of adding many features in the future, probably by June. Those features include a full-size, higher-resolution viewing screen for sharing and watching videos; a fully Web-based, download-free version of SeeToo; photo slideshows; using names to distinguish viewers; and sharing sessions that don’t time out. In addition, it hopes to let Mac users initiate sharing sessions. The site aims to be out of its testing stage by September.

Right now, SeeToo can come in handy if you know someone else is at a computer and ready to watch a video. The invited guest never downloads anything and neither party needs to register to use SeeToo. But its screen is a bit on the small side, and the service needs to become more versatile before it can be seen as a reliable sharing site.
