I heard about this a few days ago and the more I read the more I love the idea. Laptop.org has the simple vision of getting a laptop in the hand of every child in the world. This is something I began thinking about a couple years ago, that having Internet access all over the world is a necessity for 3rd world countries to survive.
While many people argued that they a roof over their heads and food to eat first, I have to disagree somewhat. Those things are critical to living. At the same time, the Internet puts in their hands the ability to learn new ways of farming and building. These guys have community done better than us Westerners can imagine. Giving them more information than they've had before can change their world.
There was even an Escape Pod podcast story about the impact this can make in Transcendence Express by Jetse de Vries. Here a teacher goes to a 3rd world country with her husband and begins introducing computers in the classrooms.
In any case, XO Giving has created an inexpensive laptop which is slimmed down to focus on doing what it needs to do extraordinarily well. The Web site does an ok job explaining, but this NY Times article really explains it all well. The idea is that for $200 I can buy one of these laptops to have them donated to 3rd world countries.
Why do you care? Well, starting November 12th, they'll have a buy one get one sale. So, if you buy two laptops, one will go to you and another will go to someone in the third world. Both of which you can deduct from taxes.
I'm seriously thinking about it for Rachel. Regardless of what I do though, this is just an incredibly smart idea which you should take advantage of.
