The XO laptop is back with a new look and a new design, at least in theory. Nicholas Negroponte unveiled photos of the upcoming XO-2 device this week, with an announcement that the revamped computer would be ready for delivery by 2010 and carry a price tag of $75. Gone is the green plastic keyboard, replaced instead with a second touch screen. The device can be opened to function like an electronic book, or it can be rotated to a more traditional laptop configuration, with the new screen assuming the role of virtual keyboard.

Intel rolled out its new low-cost laptop model yesterday, and the machines will boast bigger, 9-inch screens, 30 GB of storage and integrated Web cameras. These new Classmate PCs, which will go on sale in April for somewhere between $300 and $500, are the second iteration of Intel's answer to the One Laptop Per Child organization's cheap laptop, the XO.
