Raspberry Pi $25 PC on course for January arrival

At launch the diminutive machine will be offered in two configurations, one at $25 and the other at $35. The extra $10 gets you double the RAM at 256MB, as well as the addition of an Ethernet port for getting online. Its creators have also announced the "Gertboard," a small expansion board that can be added to the Rasberry Pi. Its purpose is to "flash LEDs on and off, drive motors, run sensors and all that other fun stuff."
