Hacking Chumby One

I came across some posts on a different discussion board about a nice Wireless internet radio clock called Chumby One. I have found out that it has linux inside and is easily hackable to be used as a robot brain. There are already sample bots out there, I have just started to look into it and thought it might be interesting for some of you. I have almost no knowledge of how linux stuff goes and I don't think I can do much with Chumby at the moment, so I will be interested if some of you guys manage to make it your robot's brain. Perhaps using Python? or Processing? Since Chumby has a USB port, connecting it to an Arduino isn't much of a problem, and I suppose by using a usb hub will let you add a webcam as well. Anyways, here are the specs of Chumby and some links of interest:

The board SF has has some advantages and some disadvantages. First, it is easier to hack, but it doesn't have the display and sound features that Chumby has. Also, it is $10 more expensive than getting it at Cosco. Of course, you need to be member at Cosco, but most of the people I know are. And I don't know too many people here. If you compare the original price of Chumby with just the board, I believe the board is good priced. Luckily for us, the commercial products loose part of the price over time, so at the moment a Chumby is a better value. I'll try to get one soon, as it is hard to use some features in a 8 bit microcontroller (mapping, SLAM, vision, etc).

There is even a balancing Chumby:

I find it funny that you can buy this at costco. Looks like a great think to hack though.
