This is a great way to help OLPC get laptops to kids around the world, as well as net yourself a cool piece of hardware at the same time. If you just want to help the kids, you can just "Give One" without "Getting One" as well.
I was in Peru a few weeks ago, and my friends Chris and Michael just got back from Uruguay, and let me tell you, the laptops are a huge hit with the kids. There are lots of pictures on the newly (re)launched laptop.org site (yes, I got roped into site maintenance and web devel, sigh).
If your talents run more to the coding side, SugarCamp starts today.
