OLPC XO Laptop gets Windows
Yesterday, Microsoft and One Laptop per Child (OLPC) announced an agreement that will make the Microsoft Windows operating system available on OLPC’s low-cost XO laptops.
Here Bohdan Raciborski from Microsoft's Unlimited Potential Group demos Windows and Office running on the XO, and mentions that performance seems reasonable - starting in a quarter of the time the original OS did. Bohdan also shows the electronic book mode.
