Hoping to recapture some of its former Walkman glory, Sony Ericsson has been busy launching a slew of music phones, which have been a huge hit overseas. The company claims some 26.5 million have been sold.
Now comes the W580, a sleek slider phone with a 2.0 megapixel camera and 12MB memory capable of 20 hours of music playback (the iPhone's built-in memory tops out at 8GB but, W580 and most phones, but doesn't allow for a memory card)
The W580 has an added bonus: a built-in pedometer that counts steps and calories for the fitness-conscious.
