The Ouya is, to me, a fascinating idea for a console and certainly has me more intrigued than a Wii U, Xbox 720 or PS4 ever could. I'll be looking into this for sure when its released in retail.
In the meantime I'm already using an Android portable with 5 inch screen with a wireless joystick playing emulators and games on the big screen. All it's missing is a name with all vowels.
