Not sure if you have heard about it. But it’s a great little computer and the demand is huge for it. The community is growing by the second, take a look at http://www.raspberrypi.org/
The pi is quite picky when it comes to peripherals, one example is keyboards. I have tested 5 different keyboards and only 3 of them worked. Unfortunately my lovely wired Apple keyboard does not work. According to some tests it’s due to the power consumption of the keyboard. I bought an external powered USB hub, a Belkin 7 port. The USB Hub did not work with the Pi. It instead killed the Ethernet of the device, however the keyboard did work.
So I returned the USB hub and bought a new one, a 4 port Noname (Deltaco) from Dustin and the one I got was flawed, so RMA on that one. My Deltaco keyboard does however work without external power, so I can finally use it at home! Yay
At the moment it runs Debian squeeze with Heezer’s rpi-updater which is an awesome firmware updater for Arch Linux and Debian.
