The SheevaPlug is a new kind of computer – a “plug computer”. At first glance, it looks like a Power Supply “brick” – the box that sits half-way along the cable between the mains power supply and your laptop, for instance. But the entire computer is contained within the “plug”, as well as a Gigabit ethernet socket, SDHC socket and USB socket.
