One Laptop Per Child won’t use Microsoft’s Windows OS on its upcoming XO-3 tablet, which will run Linux, Ed McNierney, OLPC’s CTO said on May 27th by e-mail. The XO-3 will also use an Arm processor, but OLPC is ruling out loading multiple versions of Windows on the tablet, said McNierney. “We’ve no evidence that Microsoft will make full-featured Windows 7 available on Arm, and that’s their decision,” McNierney said. Arm processors can run Windows Mobile OS, but Windows Phone 7, Microsoft’s upcoming mobile OS, was also rejected by McNierney. “Our XO tablet will be a full-function computing device, not a smartphone or a PDA. Windows Mobile was designed for those markets, not general-purpose computing, and it’s just not useful to us,” McNierney said.
An XO-3 prototype will first be displayed at the Consumer Electronics Show early next year running Google’s Android OS, Negroponte said in an e-mail. By Jan 2012, XO-3 will likely run a different Linux OS. Current XO laptops run Linux with the Sugar platform, which provides an education-specific user interface. Sugar development is being managed by Sugar Labs, a nonprofit organization.
