The Raspberry Pi project is a non-profit organization whose goal is to provide a cheap computer. And by cheap, I mean a fully functional $25 computer. The intention is to provide such cheap computers for educational purposes. Personally, it’s size, low power consumption, and price makes it ideal for projects: a brain for an Arduino (Which itself costs more then the R-Pi), a media center, a jukebox, or any other of a host of projects others have previously thought up (such as a NES emulator). I am very excited for this product to go into mass production, and I plan to get my hands on one of the units as soon as their backlog is cleared.
