A Cool video. This technology is going to advance a LOT faster than people think. This device is in the development stage, and companies are coming out with applications and using it productively already. Some of this stuff that looks really easy to use requires an enormous amount of work to make it go. They've been working REALLY hard on this and have accomplished a lot.
I'm sure there's a lot of pressure at Microsoft to get it done quickly.
Great software applications require great displays.
