How cheap can a Linux computerbe? If we are to believe the English Foundation Raspberry Pi may be just £15 or roughly $25. This includes a circuit with an ARM processor, 128 megabytes of memory, a USB port and an HDMI port for the display. There will also be support for SD memory.

The computer, which also is one of the world’s smallest, is still at the prototype stage, but Raspberry think they may be for sale within a year. The OS is a stripped down version of Ubuntu 9.04. The computer should be able to run 1080p displays, capable of OpenGL and even touchscreens.
The price is just for the bare necessities though. You will have to “upgrade” it with a keyboard, monitor and USB hub, but the sticker price away is nevertheless the lowest we’ve seen so far. According to the Foundation these little machines are targeted for schools and institutes.
