At the RCA booth today we got a quick glimpseat something they're working on. It's a 42" full HD TV, that runs Android 2.2 at the same time. The OS can be controlled from the TV's remote or with what looked strikingly similar to the Brando Rii Bluetooth keyboard. The UI is a custom media-centric launcher which allows you to view images and videos on the large screen. Around the back we found a USB port which indicates that you should be able to play external media from your own storage devices.
As you can see in the notecard, the Android TV supposedly has access to the Android Market.
