I remember reading about this device about 1 to 2 years ago. I stumbled upon it yesterday again. The Raspberry Pi is a basically a credit card sized single board computer that has capable power to run a Linux kernal based Operation System. It can even run HD video from the integrated 256MB CPU/GPU chip. I am very tempted to get one of these, just to see what it can do. Prices range from $25 or $35 dollars, depending on the model chosen. A very cool device.
