I keep wondering why Samsung or the like don't just take the guts from an Android tablet, and stick it in the back of a TV. You get an interface that people are used to and apps aplenty to do everything.
Just need a decent way to control it, as I doubt people will stand up next to their 60" LCD and use 10 point touch --
