When it comes to music mobiles, Sony Ericsson has done a great job with its Walkman range of handsets. This latest addition may not look as flash as some of its siblings, but it neatly combines impressive music skills with 3G features into a compact candybar design that's likely to have broad appeal.
The W660i is available for free on contract on most networks.
Strengths
It may not have the 'look at me' appeal of some of the other Walkman phones we've seen recently, but the W660i's two-tone colour scheme is still easy on the eye. The more traditional design also means there's room for an ample-sized keypad -- something that heavy texters will appreciate.

If texting isn't your bag, maybe you'll get more use out of the decent 2-megapixel camera on the rear, which is twinned with a smaller VGA one on the front so you can make video calls if you're using a 3G network.
Most people will be interested in the phone's music features, and here it doesn't disappoint. The phone comes with a 512MB Memory Stick M2 card, so it can hold a decent number of tunes, and music sounds great on the supplied sound-isolating headphones. Thanks to the standard mini jack adaptor lead you can swap to your own cans of you prefer, and there's also an onboard FM tuner for when you're fed up of your own tunes.

Other useful features include the ability to automatically create a photo blog with pictures uploaded from the phone, a built-in RSS news reader and support for wireless A2DP (stereo Bluetooth) music streaming.
Battery life is pretty good, too. You'll get around 6 hours of talk time and 15 days worth of standby time.
