Turns out, I was wrong. The "buy one, donate one free" program for the OLPC Project's XO laptop is in fact not a rumour, as I had said in class today:
One Laptop Per Child -- XO Giving
As geek blog Engadget says, and contrary to what some might think, this is not such a bargain. It's also not that dissimilar to what is done with medicine sent to Africa and other parts of the world. Just a bit more of a direct relationship between donour and receiver than most similar asymmetrical relationships between "us" and "them."
