British charity Raspberry Pi Foundation has unveiled a dirt cheap computer based on the ARM architecture aimed at school users.

The tiny contraption costs a mere $25 and it is about the size of an oversized USB stick. The device is powered by an ARM11 processor at 700MHz, it has 128MB of memory, 1080p support via HDMI, USB 2.0 port and a memory card reader for storage.

The Raspberry Pi can run open software, such as Ubuntu, Iceweasel, Python and KOffice.
