Hardware, Embedded Systems We all know platforms like the Beagleboard, which are cheap hardware platforms which can be used in all sorts of projects. A new entry into this market is Raspberry Pi, a British ARM board which is slated to be released in the fourth quarter of this year. For a mere $25, you'll have a fully-configured ARM-based 1080p-capable mini-motherboard. The device is still in development, and only a few days ago, the alpha version of the board was demonstrated running Quake III.

How much for a usable computer though?

As a stunt, making a "$25 computer" is cool and all, but it will take a lot more to make a functional computer and those extra parts cost the same as they do for a traditional computer.

Yes, it's a cheap motherboard, so you save a bit building a fully functional computer, but you don't save all that much. You can get a functional AMD motherboard + GPU + CPU for $70, and that motherboard will include things like SATA ports, and more than one USB port - not to mention about 4x the CPU power.

The ability to power the motherboard from non-traditional power sources is neat and all, but show me a monitor that runs on 4 AAs.

...and at least 20-30 times the power consumption, about 6 times the size (and that's talking mini-ITX), and a lot more noise since it will require cooling of some sort.

Totally pointless comparison.

And why will any of those things matter to third world educators?

Also, by the time you build a fully functional system the power consumption won't be all that stellar, as you will be powering a monitor and a HDD (third world folks aren't going to be able to afford much SSD). So you are not going to be running any usable computer based on this off of petal power, AAs or small scale solar cells.

Third world educator aren't going to much care about size and noise either. In fact, with a standard form factor they can probably pick up a housing very cheaply on the used market. Good luck finding a housing for Raspberry Pi - maybe they can fashion one out of adobe or something.
