Definitely an impressive feat. I really, really, really wish it had on-board Wi-Fi though. At least that would make it a useful web server.

The way it's designed now, it's kind of unusable for anything useful without making it a 3X larger package. Add a Wi-Fi dongle and the converter from regular to micro-USB is about the size of the board itself. And since it only has 1 USB port, you'll need a full-blown hub to connect any other stuff like sensors, keyboards, or whatnot.
