This is exactly how I feel about my Ouya. It sits on the side of my TV stand completely unobtrusively, and if friends come over within 30 seconds we can be playing frantic, immersive games. Not desperately struggling to figure out how we get a second player online without a second xbox live account. It's a shame enough people didn't realise this from the start, but $150 is not a lot of outlay for what I got in return…
Yes. This. Ouya + XMBC is amazing. While modern $99 "video pucks" like AppleTV, Roku, or Amazon are good streaming clients for NetFlix, etc, they utterly suck at playing files from a local network. Ouya + XMBC is an incredibly option for this use case, now that Boxee is gone.
Hard to beat at $35, or $29 at Best Buy right now due to a sale. That's practically sales tax on the AppleTV plus the more or less required AppleCare.
