yeah, it seems like an extension of touch screen and gestures taking the place of mouse selection, but it is the way to go imo, mice and tablets are dated, it`s about time they came up with something new, being able to invoke a keyboard and things like that add some versatility to it and it would feel more natural to just touch the close button with your finger to close a program, sketch witha fingertip or dummy pen etc.
theres another one on that site that looks interesting, they use a brush with a camera in the head to paint on the screen, the cool bit is they pick up textures or animation clips from real life objects and paint with them, I was thinking you could do that with a webcam and some tricky software to detect where on the screen the camera was pointing (like the old lightpens)
