Choosing a Portable Music Player
Compactness is one of the primary considerations of buyers. A portable device will make it easy to carry around even when you travel. However, there are other things that have to be assessed.
Storage space is important and so is its expansion capability. As a rule, it is best to pick a player that has as much storage space as you can afford. The rule of thumb is that one megabyte is equal to one minute of song. This is only an approximate though.
Aside from the mp3 player sizes, compatibility should also be assessed. Obviously it can play mp3s, but check if it can play WMA files too. If you want to play those files, make sure that the player supports it.
