From my previous post:
Now with XBMC available for Jailbroken Apple TV 2G this adds a new dimension to HTPC
● Full XBMC install, this is not a remote or thin client streamer.
● No longer is your AppleTV2 chained to iTunes.
● Who wants transcoded video anyway?
● Share files on your network your way.
● Full hardware decode for 720p/1080p movies.
● Everything else you know and love about XBMC.
