XBMC running on ARM
 

The hardware used is a Beagleboard which runs a 600 MHz ARM processor, has OpenGL 2D/3D acceleration, puts out HD via a DVI port, and is selling for about $150. The 3″ by 3″ board can be connected to a network using a USB WiFi dongle. Although integrating XBMC by hacking TV firmware is a long way off, we’d consider velcroing one of these to the back of our HDTV and getting rid of the hulking PC behind the entertainment center.

Sweet. XBMC still has the slickest and easiest, fastest and most straight forward multimedia interface of any TV connected device I've ever used.

MP3 cataloger rules, video playblack and subtitle tweaking is gold. In short: for SD content, XBOX 1 with XMBC is still a dream:)
