Fear not, OQO and Toshiba Libretto fans. There's a downsized computer for the 21st century. It's called Raspberry Pi, and if you haven't heard of it, you have to turn in your tenured engineers' pass.
The diff this time is that Raspberry Pi isn't a Wintel PC jammed beneath a Chiclet-sized keyboard. It's a tech teaching tool, propelled by the Raspberrypi.org Foundation, whose mantra is "to see cheap, accessible, programmable computers everywhere."
The Pi will set you back $35. Think you can afford it?
