The Sony Ericsson Walkman Phone range has been expanded, with the addition of the W550. The new Walkman Phone boasts stereo music and 256MB of internal memory, as well as a 1.3 megapixel camera, full Internet browsing capabilities, 2D games and Music/Video DJ software. The device can store between 60 to 120 MP3 or AAC music tracks, and can go for about 30 hours on a single charge.

The 1.3 MegaPixel camera captures stills and video-clips and adds a 4x digital zoom lens for close-ups. Images are stored or shared using MMS or Bluetooth, or backup to a PC via USB cable.
