The new Motorola Atrix HD has some seriously stiff competition in AT&T's smartphone lineup with the Samsung Galaxy S III and the HTC One X. The Atrix HD has most of the specs to match the top tier Android smartphones, but does it put them together well enough to be a real competitor?

The answer to that question is a bit of yes and a bit of no. The Atrix HD excels in certain areas, but doesn't quite hit the mark in others. Fortunately, its $99 price tag makes it a great value, and it is one to be considered for those who don't want to shell out upwards of $200 on a new smartphone.

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.
