Multiple Android-powered consoles competing against each other could get kind of ugly. It make me think of the time when multiple manufacturers were allowed to build Atari (delenda est) compatible boxes.
GameStick is yet another kickstarter getting money right now. They are different than Ouya by providing a console you can take with you. The dongle that runs it all can be stored right in the controller. Will GameStick blow away Ouya? Can this thing even be built for a cheaper price tag than Ouya?
