One notebook for each Child would not utilize Microsoft's Windows OS on its future XO-3 tablet, which will run Linux, OLPC's chief technology executive said.

OLPC's chairperson Nicholas Negroponte last year said the organization was influence Microsoft to create a full version of Windows accessible for the previous XO-2, which was also based on the Arm processor. The XO-2 was afterward canceled.

The XO-3 will also use an Arm processor, but OLPC is decision absent loading numerous versions of Windows on the tablet, said, OLPC's boss technology official, by e-mail.

"We have no proof that Microsoft will create full-featured Windows 7 accessible on Arm, and that's their choice," McNierney said.

Arm processors can run the Windows Mobile OS, except Windows Phone 7, Microsoft's future mobile OS, was also discarded by McNierney.

"Our XO tablet will be full-function computing machine, neither smartphone nor a PDA. Windows Mobile was intended for those marketplaces, not all-purpose computing, and it are just not helpful to us," McNierney said.

Obtainable XO laptops, whose major audience is children in developing countries, come with x86 chips and present Linux and Windows operating systems.

But OLPC and its partners similar to Sugar Labs have completed progress in developing power-management features in Linux and that is the OS of option for XO-3, McNierney said.
