They really lay into this thing. I called it from the start 
Conclusion:
For $99, everyone who backed Ouya's Kickstarter has unwittingly signed up to beta-test a game console. Alpha-test, even: this is a product with some good ideas and a potentially promising future, but it's a million miles away from something worth spending your money on. Even if the concept is right, the Ouya misses the mark. The controller needs work, the interface is a mess, and have I mentioned there's really nothing to do with the thing? I'm not even sure the concept is right, either: there are plenty of fun Android games, but currently few that work well with a controller and even fewer that look good on your television.
Let's say everything goes exactly right for Ouya. Every good game in the Play Store becomes available to Ouya, Netflix and Amazon decide to play nice with the device, and the ROM and hacker community explode and make every app and many more available to the nascent platform. Then and only then, Ouya can be viable — if it can combine a decent set-top box with a decent gaming platform, it may have a case to make for your $99. But those are a lot of cards that have to fall a particular way, and without them the Ouya is a lot more like a Raspberry Pi than an Xbox 360.
To its credit, the company says loudly and often that this is only the beginning of a long road for Ouya — and I'll be watching its progress with interest. But the device is currently being sold as a product, not a prototype, and that's just wrong. Ouya isn't a viable gaming platform, or a good console, or even a nice TV interface. I don't know what it is, but until Ouya figures it out, it's not worth $99.
