Nokia's Lumia 900 is the Windows Phone to watch. The U.S. exclusive represents the cream of Nokia and Microsoft's first crop, and the companies confirmed today that it will be available from AT&T this March.

The Lumia 900 boasts a 4.3-inch ClearBlack display, 4G LTE and a 1.4 ghz processor with 512 MB of RAM. Nokia announced it as something of a surprise earlier this week at CES, confirming its March launch date this morning.

Pricing for the Lumia 900 hasn't yet been announced. Nokia's first Windows Phone, the Lumia 710, is currently available from T-Mobile for just $49.99 on contract.
