I know there's a lot of hype around the Raspberry Pi, but it's interesting that you would mention it as a key component of open systems when it's a perfect example of half-closed:

* The BCM2835, the microprocessor used on the board, is not available to be purchased by hobbyists

* The full data sheet for the BCM2835 is not available without signing an NDA with Broadcom (and presumably that only happens when you have a commercial application)

* A schematic is available, but not the PCB layout

* The GPU drivers are a binary blob

The Beagleboard and the Arduino are much better examples of open hardware.

Those are excellent points, when I get home later I'll update the article. That's a big oversight on my part, thank you.
