The claim comes ahead of the anticipated Windows Phone 7 launch next week, which is expected to be supported by handset manufacturers including HTC, LG and Samsung.
Ballmer said Microsoft’s strategy is to “cover all form factors” and that Windows tablets will be on the market soon.
“You’ll see new slates with Windows on them. You’ll see them this Christmas. Certainly we’ve done work around the tablet as both a productivity device and a consumption device,” he said.
