I gotta say though... this doesn't seem particularly unvaporish either... their prospects for development seem downright bleak and their site hasn't changed a bit since the last time I visited (2002). Also, the fingerworks model doesn't incorporate a screen and touch in one. I guess what I'd really like to point out/ask is; how many of these types of interfaces have people actually encountered? The solution (vapor or no) seems to be a step in a positive direction that the computer industry should take cues from.
