Game developer David Braben has built a computer that's the size of a USB stick and costs $25, called the Raspberry Pi.
The computer has one port on either side: just plug in a screen and keyboard, and off you go. The computer has a 700MHz processor and 128 Mb RAM, which is really impressive considering size and price.

The video is worth a watch as David raises some very interesting points.
