Ouya launches today in North America and the UK. The Android console can now be purchased through Amazon, Best Buy, GAME and Target for $99.99. Extra controllers will run you $49.99 each. It comes with over 170 free-to-try games, Twitch.tv, TuneIn and Plex as well as the Make Channel that allows developers to build and test games. It has already sold out on Amazon, and many who pre-ordered via Kickstarter are still yet to receive the system. Thanks, Polygon.
