The Foundation that manages the One Laptop Per Child Program (which will give one low-cost, Linux-based laptop to every child in the developing world — eventually) is making their machines available for sale in the developed world this Christmas. The price is $399, and includes two laptops, one of which will be given to a child in the developing world. I've just signed up to get one — I just wish that this was structured as a donation to the Foundation, since I think they'd sell a ton of these if the purchasers could get a tax-receipt for them just before the tax year closes.
Starting November 12, One Laptop Per Child will be offering a Give 1 Get 1 Program for a brief window of time. For $399, you will be purchasing two XO laptops–one that will be sent to empower a child to learn in a developing nation, and one that will be sent to your child at home. If you're interested in Give 1 Get 1, we'll be happy to send you a reminder email. Just sign up in the box to the left and you'll receive your reminder prior to the November 12 launch date.
