John Lennon wants you to change the world, all you need to do is help educate a child in a developing country. The Lennon advertisement isn’t actually asking that you go teach in a developing country, but rather participate through the One Laptop Per Child (OLPC) non-profit initiative by donating a laptop. The XO Laptops, created by OLPC, are built and designed for children in developing countries. These laptops quickly charge using a solar battery charger, they standup to water, and come with unique software aimed to encourage learning. The exciting part of the program is that for the next few weeks you can get one of these laptops for your child through the Give One. Get One. program.

If the One Laptop Per Child initiative is completely new to you, I recommend watching the short video below to get a better sense of their mission. A longer video that really shows Nicholas Negroponte’s passion behind the OLPC and showcases the laptop can be watched at the TED conference.

Earlier this month, Nicholas Negroponte flew to Colombia, along with a team from One Laptop per Child, to deliver bright-green XOlaptops to schoolchildren in territory once held by guerrillas. TED came along to film as part of a new, occasional feature called “TED in the Field” that offers updates on TEDTalks speakers and the initiatives, ideas and products they announced. Negroponte talks with TED about OLPC and what he’s learned along the way — and invites TED viewers to take part in the Buy One Get One program.
