On the outside, the Windows version of the XO laptop looks just like the Linux model. But simply booting up the device shows that the Windows version bears little resemblance to the original One Laptop Per Child device. With the Microsoft version, you get Windows, for all the good and bad that entails. It's full-on Windows--XP Professional, in fact--and can run basically any software that can adjust itself to the mini-laptop's diminutive screen and modest processor.
