Bah dimwits, all of you. Except Death - you're just weird for not wanting one! There's a 1GHz CPU on that thing, which is about as high as you can go with passive cooling (no fans). Chuck in some solid-state storage like an SD card, and you have a 1GHz, completely silent PC that could fit inside your mobile phone!
Think of the possibilities! Build a PC into your monitor (even an LCD monitor). You could fit one in the dashboard of your car (runs off 12v DC) - add a GPS receiver, google earth, an mp3 player and some other goodies. Build one into your external USB harddrive - instant file server! Hell it's so small you could probably have one implanted under your skin and not notice it. Might experience some discomfort when playing
WoW (could get hot) and you might want to think twice about where you position the VGA connector...
