Nokia Lumia 928
The Lumia 928 is an all-around solid phone, with a sharp, 4.5-inch AMOLED display, a good 8.7-megapixel camera, and a remarkably bright xenon flash. The real reason you'd pick this model over another free-with-two-year-contract smartphone is Windows Phone. Whether you're in love with Microsoft's phone interface (not unreasonable, considering how slick its big, colored tiles are, compared Android's and iOS's dinky rows of desktop-style apps), or want to access and edit Office, Excel and other Microsoft-based files without worrying about garbled formatting, the 928 is a workhorse well worth its non-existent asking price.
Standout Feature: It's a Windows Phone
