The Redmond, Wash. company had earlier announced that its own , based on Windows RT, will ship Oct. 26, the day Windows 8 is set to go on sale.

Some of the OEMs (original equipment manufacturers) listed by Microsoft as Windows RT partners had earlier publicly revealed designs or said they would deliver hardware based on the new operating system. Others not named by Microsoft, including Toshiba and Acer, had also announced plans previously.

In a post on the blog Monday, Mike Angiulo, the vice president of Microsoft's ecosystem and planning team, declined to go into specifics of each OEM's planned products -- he left that for the vendors to do themselves closer to the October launch of Windows 8 and Windows RT -- but he did spell out some specification ranges for the new hardware.

The upcoming devices will include both tablets and laptops, and run the gamut of form factors. "Some of our Windows RT PCs come with full keyboard and touchpad solutions, whether removable/dockable or a traditional clamshell," Angiulo said.

According to Angiulo, some of the new Windows RT devices will be up to 11% thinner than Apple's iPad, and weigh 20% less than the Cupertino, Calif. company's iconic tablet.
