The XO laptop is back, and sports a new design. Nicholas Negroponte, the originator of the One Laptop Per Child (OLPC) initiative, unveiled photos of the revamped XO-2 device this week, and stated that the new notebook computer would sell for $75 each and be ready for delivery by 2010. The OLPC group claims that the rapidly decreasing prices of flat panel technology will make this price feasible.

Changes to the XO design include the replacement of the green plastic keyboard with a second touch screen. Also, the laptop can be opened for use as an electronic book (for sharing with others), with the keyboard function assumed by the new screen; or it can be rotated to operate as a traditional laptop.

The XO-2 design also will use less power and be one-half the size of the original XO. Its OS will still be open source Linux-based, but will also have a dual boot option for loading the Windows OS.

In addition to the new XO, Negroponte announced the return of the Give 1, Get 1 program in the U.S., where U.S. customers can purchase a laptop for a child in the developing world at the same time they purchase one for themselves.
