For reference, the Raspberry Pi is a cheap (circa £20) circuit board comprising everything you need to get a Linux bare-bones PC up and running - you add a USB power supply (5V @ 1.2A required), USB keyboard and mouse, and run an HDMI output to a TV for the video out. The OS needs to be downloaded and installed on an SD card. The intention was to give present-day children something of the experience many of us olden-day children had with the Nascom, ZX80/81, Spectrum, BBC Micro, etc - in other words get to understand computers and programming from the ground up instead of just using them as a domestic appliance. There has already been discussion on the forum about using one as a media streamer [Raspberry Pi DLNA Client], but as more general chat about the RPi is off-topic I've started this thread in the 'Arms. There are lots of resources on the Web of course, and there are large review articles in the August PCPlus and EPE.
