With the SonyW300 the clamshell design is introduced into the walkman series. This means that lots of space is saved and the whole design is slimmed down to such an extent that the phone becomes incredibly lightweight. When it comes to making the cell phone experience easier for the user, there is no better master than Sony who have been making phones for years. This full featured phone has all the best aspects of Sony’s previous releases and improves upon them considerably for a phone that’s ready for a new generation of cell phone users.
