Meh, not too impressed by it. At $10,000 I can't see how that is more efficient than a Laptop setup somewhere.
And you just know it won't just download photos from your camera instantly like it shows, send email without even putting in an email address (the postcard), and recognize your cellphone in less than a second. Oh I liked how it recognized the girls Zune too, funny stuff.
I don't think it's really a replacement for a laptop at this point.....
And come on, we do know multitouch is the future of interaction. Apple knows this; the iPhone is just their first multitouch device. I fully believe that Apple is pushing it out across the product line too.
Clearly a lot of the stuff in those videos are concepts; would probably require that devices included support for the concept (which would be a big if). Although how much support would be required is another question. If the MS Surface device can at least tell from, say, a bluetooth or wifi signal what device it was, it could pull the rest of the info it needs from the Internet (for things like that phone product comparison thing).
