One Handed Portable Game Console

I was thinking of how convenient a portable game console designed to be played with one hand would be like, you could play a game with one hand and have a hamburger with the other hand, or take notes, or having a drink, or standing in the bus, or even playing it while making a phone call, it would be like a portrait mode device, with a button layout similar to an old cellphone or portable MP3 player, like a trackpad with embedded buttons, buttons on the back too for extra control, an accelerometer, and it could be played with your right or left hand, it could feature games like RPG’s, turn based games, puzzle games, point and click adventures, simplistic platformers, arcade style games, etc. and the games would be released digitally.
