I like the idea, not that picture.
Switching your game over from the tv to the controller whenever you want is a brilliant idea. Many times I've wanted to do some b-spec races, assasin contract assignments or just browse the store and download a game while the tv is in use. Doing some sidequests on the controller, then switch back to the tv for the full experience in the main quest sounds great to me. Should be cheaper then my other option to buy a 60 inch 21:9 tv with dual tuner.
