WALK, TALK, RUN, ROCK
Fitness fanatics, listen up: This audio-focused, 3.3-ounce slider phone is the smallest, lightest device we tested—a stellar running companion. On board you’ll find a two-meg camera and a fitness app that can count steps, gauge speed, and monitor calories burned. Once we swapped out the puny standard card for a four-gig, testers were surprised by the sound quality of such a tiny thing. At first we thought the “shake” feature, which lets you jump to the next song with a flick of the wrist, was pure gimmick—then we went running: It’s a no-brainer to skip a track when you need to keep your eyes on the trail. 3.3 oz; 512MB card; Bluetooth; sonyericsson.com
