Socket FM2 is (almost) there

From what I remember reading about it that is a charity organization that makes some very cheap, and inexpensive tiny computers, little bigger than a credit card (but of course a bit thicker).
They have an ARM processor and something like 256Mb of RAM, run Linux and can be powered by AA batteries (or AC plug). By far NOT the most powerful thing out there but sufficient to plug to a monitor and have a very basic web browsing machine.
I think it's a great idea for underprivileged families and/or 3rd world countries where you don't have much access to technology, but I wouldn't be able to do anything with one myself.

If you want to crunch using ARM chips, this might be an option
