The price of Nokia's flagship U.S. Windows Phone device, the Lumia 900, has been slashed from $99 to $49.

The price of Nokia's flagship U.S. Windows Phone device, the Lumia 900, has been cut in half.

The smartphone is now available on AT&T's website for $49.99 in blue, white, black, or the with a two-year contract.

The Lumia 900, formerly $99, features a 4.3-inch screen and packs a 1.4-GHz processor along with an 8-megapixel camera with Carl Zeiss lens.

The phone come fall, but it will go to Windows Phone 7.8, which improves the phone's start screen but doesn't include new APIs for more powerful apps.

Microsoft is still struggling to make a dent in the mobile market, . Its aging Windows Mobile platform actually outpaced the newer Windows Phone at 3 percent vs. 1.3 percent last month. Despite Microsoft's close ties to Nokia, meanwhile, most Windows Phone users are using Samsung or HTC devices, both capturing 0.5 percent to Nokia's 0.3 percent.

Of those who have purchased a Lumia 900, however, it appears that most are happy with their device. A recent survey of U.S. customers conducted for Nokia by the independent research firm Nielsen, found that 96 percent of Lumia 900 owners are extremely or somewhat satisfied with their device, and 95 percent would recommend it. Eighty-three percent said their expectations of the device were exceeded.

It's not entirely shocking that a Nokia-commissioned study found that people love the Lumia, but the findings are consistent with responses from PCMag's Readers' Choice Awards.
