The UK company Jade Integration is about to release a PC that is small enough to fit inside a standard wall power socket. Not only that, it can be powered solely over ethernet.
Called the Jack PC, the guts of it consists of two layered circuit boards and is powered by only 5 Watts. The face contains a VGA port, 4 USB ports, an audio and a microphone port. The CPU is an AMD RISC processor which is the equivalent of a 1.2GHz x86 processor (think standard Intel or AMD chips).
The main purpose of is to run a thin client to connect to a server so you can do most of the processing off of this device. Also, Internet Explorer 6 is included to access web applications such as your gmail or gcal.
The Jack PC gets its official launch the 14th of June at the IT Works Show.
