Photos: Low-cost PCs

The Classmate PC (left) is an Intel-designed laptop with a 7-inch screen and flash memory instead of a hard drive. It is designed for use by youths in developing countries.

Teachers will be able to conduct lessons on laptops while students follow on the Classmates. If students try to surf the Web while class is in session, the computer will block them and warn them politely to pay attention.
