And the whole thing feels very Nintendoish. Why did nobody think of that before? The Sharp phone is about as relevant prior art as the Microsoft Sidewinder thing was for the Wii. It will be hard to get right, and their games will be head and shoulders above the rest.
One hopes. I brought up the Virtual Boy earlier as a joke, but at that time Nintendo couldn't really come up with a convincing use-case for 3d (much less 'virtual reality').
I still haven't been convinced that it isn't just a gimmick. Not that this won't sell, but then the 'DS' name might guarantee that.
