I bet you would end up never using the controller thing, too much of a hassle when you can just slide your finger on the screen. The projector was cool, Although I'm not sure when I would ever use that also.
what tech on that phone is impossible for the immediate future? the only thing that would need development is syncing the dongle with the projection... everything else already exists on different devices, just needs to be integrated into the single package.
I think I just jizzed. the only flaw i see is the headphone jack location, you might destroy the connection point if you keep the phone in your pants pocket. other than that I would gladly steal candy from a baby to get that phone!
