The MP3 revolution has changed music distribution for ever. Those of us born the wrong side of 1980 will remember the excitement of the original cassette driven Sony Walkman. These days it is possible to store your entire music collection on a single device and carry it around everywhere you go.

The modern media player is capable of playing movies, taking photos, connecting to the Web and all the other things you expect from a portable device like this. There is clearly a strong overlap with Smartphones but the PMP still has a place in your pocket.

Personal media players are more affordable, more specialised and you don't have to worry about not being able to make phone calls when your battery runs out!
