NEW YORK (AP) - Microsoft is introducing new Surface tablet computers and accessories, including a professional model that allows people to use it more like a laptop or a desktop.

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. The kickstand built into the device is redesigned to make it easier to use on laps. In the past, it worked best on a flat surface such as a table.

Microsoft says the Pro 2 also offers a 75 percent improvement in battery life over the previous model. 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.

Microsoft didn't immediately announce prices or a release date.
