Since Microsoft introduced Windows Phone 7, they have tried in vain to introduce a legitimate competitor to the Apple iPhone. They have also failed to unseat an army of Android devices. Nokia's entry was an all-in gamble that was supposed to platform among the elite of smartphones, but being the most popular of the bunch didn't translate to commercial or critical success.

In the Nokia Lumia 920, Windows Phone 8 has a worthy competitor to iOS and Android. It continues the design philosophy that made the original Lumias the most popular Windows Phone handsets. It also features brand new software that is faster and more robust than its predecessor. Will a winning hardware foundation and vastly improved software secure the Lumia 920 a place among the elite?

The Nokia Lumia 900 represents a number of firsts: it is the first high-end Windows Phone from Nokia to arrive in the U.S., it is the first 4G LTE smartphone from Nokia, and it is one of the first 4G LTE Windows Phones on the market.

Like the Lumia 800 that preceded it, the Lumia 900 features stunning industrial design, great build quality, and a fantastic ClearBlack AMOLED display. Add in great network performance, solid battery life, and a fast and fluid user interface thanks to Windows Phone 7.5, and you start to see that Nokia really might have a winner on their hands.

The Lumia 710 represents Nokia's first Windows Phone 7.5 smartphone in the U.S. Thanks to a fast processor and Windows Phone's attractive and snappy interface, the Lumia 710 is no slouch when you use it, and the phone benefits from solid call quality, decent battery life, and a usable camera.

But is the Lumia 710 capable of making a splash in the crowded U.S. smartphone market, or if it just another forgettable, entry-level device?

One of the problems we've seen with Windows Phone devices thus far is that if you've seen one Windows Phone, you've basically seen them all. Or so we thought...

Nokia has proven to the industry that it can do Windows Phone better than the competition. Its Lumia 800 features one of the best hardware designs found on a smartphone today -- on any platform. In short, it's a fantastic smartphone that truly takes Windows Phone to the next level.
