I say a car computer. I have been looking at converting a EEE 700, 701, or 702, but these machines are really compact little beasties. This might work in a pickup, SUV, or possibly a van.

Though if I were to go with the seperate CPU path, I would want something that is compact enough to fit in my glove box, as I drive a station wagon, and I need my cargo space.

I might just give up and put a core solo mac mini in it so I can have the remove control, but the thing is gonna have a touch screen anyways, and the IR reciever might be blocked by the fact it will be in a closed box.

these go for over $200 at micro center, so nice going!!
