A long way back, during Google I/O, there was an option for developers to register to get an Android TV Dev Kit. I had long forgotten, until all of a sudden FedEx showed up with one for me. Thanks Google, I will start developing as soon as I can come up with some ideas!

I'm looking forward to these things being a real product I can buy, so this is good to hear!
