Microsoft is going to offer new tablets powered by its Windows 8 operating system

Tablet computers work mainly with Google's Android or Apple's iOS software. But Microsoft is hoping to change that with new tablets powered by its Windows 8 operating system.

Computer makers including Acer, Asus and Toshiba have announced new tablet computers that offer a host of features, such as an optional keyboard. Most notable, however, is the use of Microsoft's next-generation operating system, designed specifically for touch screens.

Dean Gallea, Senior Program Leader for Consumer Reports, made some interesting observations during a preview of Microsoft Windows 8. The new operating system, expected later this year, promises to deliver an iPad-like interface, with on-screens apps and an app store similar to the iTunes Store and Google Play. And Windows 8's new Metro touch-based interface could offer some compelling man-machine interaction—especially since as more traditional desktop, laptop and ultrabook computers become equipped with Microsoft's new operating system and touch screens.
