Nokia Lumia 710 compare (black, T-Mobile)

The $49.99 Nokia Lumia 710 is an excellent way to get the growing capabilities of a Windows Mango smartphone for a rock-bottom price. Though it isn't an Android superphone with a luscious AMOLED display, it's a practical device that covers all the mobile bases.

Nokia's Lumia 920 is heavy and thick, but if you want the most powerful, feature-rich Windows phone available, this is it.

Nokia's Lumia 521 is one of the best bargain smartphones on any platform, but skip it if LTE is of paramount concern.

A few quibbles notwithstanding, the powerhouse HTC One is a beautifully crafted, near-ideal smartphone.

The iPhone 5 completely rebuilds the iPhone on a framework of new features and design, addressing its major previous shortcomings. It's absolutely the best iPhone to date, and it easily secures its place in the top tier of the smartphone universe.
