How is the group, called One Laptop Per Child (OLPC), able to create a laptop so inexpensively? It is mainly a matter of cleverly combining existing technologies in new ways. The laptop will have a basic processor made by AMD, flash memory instead of a hard disk, will be powered by batteries or a hand- crank, and will run open-source software. The $100 laptop also puts all the components behind the screen, not under the keyboard, so there is no need for an expensive hinge. So far, OLPC has got the price down to around $130.
But good news for the world's poor, may not be such great news for the world's computer manufacturers. The new machine is not simply of interest in the developing world. On September 22nd, Mitt Romney, the governor of Massachusetts, said the state should purchase one for every secondary-school student, when they become available.
Sales to schools are just one way in which the $100 laptop could change the computer industry more broadly. By depressing prices and fuelling the trend for "good-enough computing", where customers upgrade less often, it could eventually put pressure on the world's biggest PC-makers.
