Wow, that's a pretty cool little computer. It looks like it's small enough to fit in the glove box.
The one thing that caught my eye: it already runs on DC, so you wouldn't need an AC/DC inverter.
The one thing I didn't like: it uses the Intel 810 chipset, not the newer, better 815 chipset.
It looks like it's called the "Mini Book". I woulnd't mind getting a bare bones model if I could find one. I'm sure the reserve on the Ebay auction is over $500, since it comes with a processor, memory, and HD.
