"One Laptop per Child (OLPC) is a new, non-profit association dedicated to research to develop a $100 laptop—a technology that could revolutionize how we educate the world's children ... Our goal: to provide children around the world with new opportunities to explore, experiment, and express themselves." - OLPC web site
