Looks good, but USB client only and no wifi connectivity makes this dead on the water for me.
The idea of a completely opensource hardware platform is great though! I hope that they can add a few features for a little extra cash. Buying a completely standalone linux machine for $100 US is a tough sell. The zipit is a similar platform with Wifi for less than $50, and those aren't exactly flying off the shelves, even though the platform is (mostly) open now.
It's got a way to go, but I'll be watching it!
Kinda makes me wonder what ever happened to the iKit thingy.
