Think about it—an inexpensive Linux PC crammed inside a wall-wart plug. Something like this SheevaPlug could open up a whole new framework of managing and sharing data that could be accessible to the masses.
Inside the SheevaPlug you will find a 1.2GHz, ARM-based Sheeva embedded processor, 512Mbytes of FLASH, 512Mbytes of DRAM, gigabit ethernet and a USB 2.0 port. Plug it into a wall socket and bam—a fully-functional Linux server that can store digital media accessible remotely via the internet or function as a remote print or web server. Plus, it supports "multiple standard Linux 2.6 kernel distributions" and it operates on only 5-watts of power. So running and developing software for the platform should be easy (and there should be substantial savings on your power bill).
Currently, open source tinkerers can get the $99 SheevaPlug development kit on the Marvell website. Several products based on the design (like the Pogoplug) are expected to arrive in the near future with price tags ranging from $79-$99. Eventually, Marvell expects the price for these devices to dip below $50. [Marvell and WSJ via Tech Report via Slashgear]
