Me too. My real pet peeve with the PC/Multimedia world is that I can't watch TV on anything other than Windows Media Center- all the channels coming through my cable connection are locked.

It's fantastically annoying, because MythTV+XBMC would be a perfect TV watching solution. As it is, my best option for a set top box is to buy an Xbox 360, and I don't particularly feel like doing that.

I'm running xbmc on my Pi (the old one, not the shiny 512 MB version) and it's generally fine. The UI is decent enough (I'm told that fancy themes wouldn't work?) and my biggest concern is the time it takes to start a movie/music file over the network, something that the Pi's not responsible for..

I was at a developer meet the other week and someone from Ouya said they have been giving the XMBC team support and it is apparently working pretty well on the device.

Plex really needs to make an Android app for the TV experience. Similar to what they do with their desktop based player.
