Sony Ericsson W580i 

The Sony Ericsson W580i is a slim and snappy music phone with a design that is a careful balance between features and price. The product has practically no high-end features, such as 3G connectivity for speedy Internet access, 3 megapixel camera, or GPS, but it comes with everything that makes it an excellent mid-range phone for everyday use.
The W580i has, however, a hardware component that has been used for two novel features. An accelerometer allows the user to measure walking (or jogging) distance and speed. This mechanical module resides inside the unit and has to be calibrated to the user’s stride. The W580i comes with a fitness application that takes care of the calibration and then measures distance and speed, counts calories, and displays the information on the screen. The Walkman music player on the W580i makes use of the built-in accelerometer, too. When the music player is on and you shake the phone, the songs in the playlist are shuffled. It is a snappy feature for users who frequently like to shuffle their playlists. But, selecting songs from the menu is not difficult, either.
