I'd like a little thing like this. Slap linux on it, stick it in a little case and it would be a great little dedicated server box, despite the furnace x86 chip racking up your electricity bills.
However, it lacks too many ports. Lack of a serial alone port is fatal, and parallel means I couldn't use it as a print server.
So it's nice, but not practical. I don't see what niche it could fill. Gamerlamers are only interested in big, hot, noisy systems anyway.
