Sony Ericsson Xperia Active
As its name implies, the Sony Ericsson Xperia Active is designed with those with active lifestyles in mind. It features a compact design with a 3-inch Reality display powered by Bravia, and still manages to rock a 1GHz Snapdragon processor. The Active is designed to withstand the elements, and is both dust and scratch-proof. The water-resistant phone sports a cool trick known as wet-finger tracking, which allows you to still use the touchscreen even with wet fingers.
The Xperia Active supports ANT+, and comes pre-packaged with a suite of lifestyle apps for the sporty, including an on-screen heartrate and pulse monitor. It's the perfect gym buddy with Android inside.
