NEW YORK (AP) - Microsoft introduced new Surface tablets, including a professional model that allows people to use it more like a laptop or a desktop computer. The Redmond, Wash. company is trying to boost its tablet business as sales of traditional desktop and laptop computers decline. The Surface Pro 2, unveiled at an event in New York, is targeted at professionals who want the full power of a laptop in a tablet-style device. There's also a new cover accessory that extends battery life even further. An optional docking station allows the Pro 2 to be used like a laptop. A cheaper model, Surface 2, offers a better screen and other improvements over last year's Surface RT. The Surface 2 starts at $449, and the Surface Pro 2 at $899. It is available starting on Oct. 22 in the U.S. and other markets. Microsoft plans to release an update to its Windows 8 operating system on Oct. 17. The screen on both new Surface models remains at 10.6 inches, measured diagonally. Microsoft didn't announce smaller Surface models. The redesigned Surface tablets come at a time of transition for Microsoft. At a time when personal computer sales are falling, the software giant is trying to become a more diversified software and mobile devices company. Earlier this month, Microsoft struck a deal to acquire Nokia's handset and services business for $7.2 billion. The company is also searching for a new CEO to replace Steven A. Ballmer, who announced last month that he plans to retire within the next year. Microsoft absorbed a $900 million charge in the April-June period to account for its expected losses from the Surface RT after it slashed prices to stimulate demand.
