The video with most gaming potential: Microsoft Surface

How often do you ever transfer photos from one camera to another?

Last I checked it's much more convenient to get them in your mail than on your limited SD card. And last I checked I store my pictures on my computer because I have about 20gb of it. Or even an archival dvd.

Point is you never have to get photos from one camera to another. If you want the pictures from your friend's camera she'll email them to you and save you having to transfer pictures to your computer. Or even just give you the SD card.

With photos the future is printouts. They're already pretty cheap and it's much more convenient to see them all in hardcopy. Secondly if you're viewing them digitally you'd look at them one by one, in full screen, for maximum clarity, unless you're an idiot.

What else was in the video? Oh yes, I'm sorry but I still don't plan my evenings digitally, as difficult as that may be to believe. I can remember all my appointments in a single day. Anything beyond that I can use web calendars.

And I doubt they'll get it to scan credit cards, highly doubt it. The screen itself might be interesting but the uses in this video are impractical. The different viewing angles will bother people a lot. What's already better is having a bigscreen tv hooked up to your computer and a wireless mouse/keyboard. Look at pictures and go on the web and show your friends. You can already do this with nintendo wii as well.

HP just shat themselves. They still haven't announced they can do multi-touch with their similar product.

This idea (of a multi-touch HCI) is being developed congruently by several companies, but the most advanced version has been built by an spin-off company from a group at MIT, Perceptive Pixel.

That demo video made me cream my pants.

To all the people suggesting it wouldn't have a use for gaming outside of an arcade, huh? IMHO, these devices will effectively spell the end of our current interface systems.

Need to type a letter? Bring up a keyboard you've customized to your specifications. Need to control a character in an FPS? Customize a set of buttons for movement and interaction, leaving out all the keys you wouldn't use on a normal keyboard. For look, you could have an area of the screen you'd use like a mouse, or something entirely new. Want to pick up/manipulate/examine an object in the game world? Do it.

And keep in mind the screen is a real object in the real world. You can angle it upwards so you're looking at it like a regular computer screen. No cat problems.

I'm kinda dissapointed in Microsoft with this, I mean I know this is really their old work just making it out into commercial use and the features are hot but doesn't this thing just pass as a pc with a touch screen and wireless stuff, like I really doubt the Zune would automatically start interacting by just placing it on the table (obviously you'd have to put it into some kind of wireless transfer mode) and the same goes for the other devices, along with the credit card (which probably has to be made to work with the machine). I dunno, I expect more from them, give me virtual pictures I can actually pick up and hold or mabye a cheaper version of this machine that won't cost over $500 and make my back hurt over time then I may actually see some hope beyond fancy shop/restauraunt in this.

And regarding game functionality I'd just wait for virtual reality, there's not much beyond turn based games and pong that this thing could really do, I'm waiting for a version of Halo where I can actually pick a gun up off of the floor and feel it's weight in my hands and feel shots hitting me (not real pain, something more like rumble).
