I have to say...that's impressive!
Yeah, it's a bit slow but, I'm sure that'll change soon.
But, to have a box THAT size (4" x 4.3" x 1.2") with THREE USB ports, built-in video (VGA out), built-in sound (Line-out and Mic-in), built-in serial, RJ-45 for network AND 802.11b/g, and an internal 2.5" HD...that's just amazing. And....AND...it runs on 12V so you could easily power with a basic Carnetix P1900 controller or something.
It's not upgradable (even the memory is soldered onto the board) but, that's still a lot of machine in an itty-bitty box for $335.00!
