The Give 1 Get 1 program OLPC last year ran for six weeks and generated sales of 160,000 XO laptops, an OLPC representative said. More people opted to give the device outright, so over 100,000 of those laptops went to school kids in countries including Haiti and Rwanda.

"The phenomenal success of last year’s Give 1 Get 1 program created tremendous demand from both the public who wanted to give more and from countries that saw an opportunity to attack poverty through education," said Nicholas Negroponte, founder and chairman of OLPC, in a statement.

There are several ways to participate in the Give 1 Get 1 program.

In Give 1 Get 1, people pay US$399 for two XO laptops, one sent to a child in a developing country and the other sent to the donor. Those who don't want an XO can also simply give as many laptops as they want at $199 each.
