Has to be an ipod shuffle. Tiny, yet incredibly easy to use which is perfect for changing tunes on the run. ITunes is a fantastically easy and reliable piece of software, which allows you to manage the music on your ipod in a very user-friendly fashion. If there is one thing I have learned from other digital music players, it is that if the software is badly designed you may as well leave the player in the box. ipod shuffle is next to indestructible also.
