Target price: $75
Nicholas Negroponte, founder of the One Laptop Per Child Foundation, revealed plans for the new computer at the Massachusetts Institute of Technology Media Lab yesterday. Due for release in 2010, the new machine will be smaller and lighter than the foundation's current XO laptop, which went on sale last year.
But the new device will feature two video display screens, one of them replacing the keyboard found in other laptops. The screens will be touch-sensitive, and can be configured to act as a traditional keyboard. But the screens can also serve as a single large viewing area.
