Vacuous demo there

I couldn't stand to watch the videos more than once but didn't the voice over say something like "live in a world of leisure where entertainment is king!" Yuck!

There were a couple of interesting things in there but what they showed over and over and over was moving, rotating and scaling photos. Have they nothing more interesting to show?

Anyone who finds the MS demos exciting, should most certainly take a look at "the real thing" at http://www.perceptivepixel.com/ -- there is FAR more conceptual depth shown there. And there are far more interface concepts than "drag with a finger instead of with a mouse." There are several examples of manipulating 3D structures, as well as using multiple fingers on both hands and having TWO people working at the same screen... either on their own objects or TOGETHER with the other person.
