We've recently seen a computer in a keyboard, but Marvell is going one better and releasing a new hardware platform that promises a computer in a plug. The SheevaPlug platform consists of the company's Kirkwood processor, 512MB of DRAM, 512MB of flash memory, a Gigabit Ethernet port, and a USB port, all of which can fit in the size of a wall-wart-style power adapter. SheevaPlug devices run on Linux, and Marvell claims they use only a tenth of the electricity that a typical home server unit taps.
Marvell is also offering the SheevaPlug development kit for $99, which includes the SheevaPlug computer. Whether this whole concept will fly is still to be determined, of course, but you have to give Marvell credit for "plugging into" something a little bit different.
