I got the Ouya as part of the kickstart more as a xbmc/CM project than a game console. I figured I'd try a few games, and maybe like it enough to buy another for gaming. Boy I was I wrong.
It requires a credit card to even finish booting. That's annoying in and of itself as it's billed as an "open" device. To make matters worse their bloody device won't actually take my credit card number. "Problem sending to server" Neither will their web site which hangs. After a day of trying to actually use the Ouya as a gaming console I gave up. Ouya support never responded to any of my support requests beyond automated responses.
The sad thing is I like the idea of the device and would have bought a game or 2 just to play around with it. Now the principle of the matter is such that I have to hack the device. Which is ironic to do so for a device I bought merely to get the device to boot up. It's not exactly hard to hack given it has abd enabled over usb out of the box. But if you intend to use this as a gaming console based on my day with it good luck.
BTW- If you are stuck with abject failure of the Ouya credit card validation like me you might try looking up the test numbers for various credit cards as the Ouya seems to accept them without issue. Obvious unless someone at Ouya is a complete idiot you won't be able to buy anything with them, but it does get you past the credit card validation and allow you to use the device with free sideloaded apps.
