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.
