Nice video! It really shows the perceptual difference well.
However, I'm not sure it's fair to call it a "touchscreen" when it's most likely a touchpad input surface aligned with an overhead projector. It's impossible to say from the video how feasible it would be to achieve the same performance with an actual touchscreen, let alone a high-resolution mobile device. But I'm looking forward to it. :)
