This is for me the same issue as, the wii controller and kinect, sounds like an awesome idea, but in reality will be a total disappointment. I cannot see anyone playing a good game of minecraft using just their finger. I'm sure you could use a controller, but again the whole demonstration is just a AR version of kinect. Gaming doesn't really want this no hands controller type system, I think the market has already spoken.
In terms of science, business and learning, I think the device is an awesome idea and could if it works be revolutionary (the UI implementation and control is massively important). If you could connect multiple ones together in terms of wireless, or even as a device to walk around a museum and it explains things it could be great and much better than the horrible VO headsets.. I can really see this having a lot of benefits in so many non gaming situations. In gaming, sorry just no.
I do wonder how light it is, and how long it will power.
Finally, after the whole kinect can scan in your skateboard or clothes, I aint believing anything shown on a video that isn't live recorded gameplay.
