The Beagle Bone is an open source hardware platform about the size of an Altoids tin. Simular in appearance to Arduino, but running Linux and with more horsepower. Of partiqular interest is that includes node.js and Cloud9 IDE, meaning that:

Too cool! I'm thinking that this could make an interesting platform for CNC or 3D printing.
I'm waiting for adafruit industries to get stock them -- expected early December.
