I just came across this nifty little ARM GNU/Linux device aiming to sell with a target price of $25 – the Raspberry Pi.

It boasts some pretty powerful specs : USB2.0, HMDI out, RJ45 Ethernet on board, SD MMC and most interestingly the ability to play HD video.  This could make a feasible XBMC replacement for my ageing desktop multimedia PC, streaming video and audio to the TV.
