We’ve discussed the Ouya before. It was initially an incredibly well-funded ($8.5 million from 65,000 backers) Kickstarter Game console project based on Android that costs $99. The hardware is similar to a Nexus 7 with a NVIDIA Tegra 3 processor, 1GB of RAM, and 8GB of internal storage (expandable via USB), but that outputs to a 1080p display.
Along with games (which are all free to try), Ouya allows streaming apps such as Twitch.tv, Crunchyroll, iheartradio, TuneIn, XBMC, Plex and Flixster, so your $99 is getting some solid features right off the bat.
Reviews are in today, and it appears that it is still a little rusty but has serious potential.
