iPod HIGHLY recommended. as Gamemaster said. it doubles for many other uses.
I have a 30gig one. i can store all my music. then put say some files on it (big ones) take it to afriends computer and put them on there without needing CD's or anything
Not to mention it plays games on it. (ex. bricks (kinda like pong)... solitare, etc. i think they can make more for download. not sure bout that yet.)
has callender. Alarm clock
you can save mesages in there and all that.
i've never regreted getting it. and its so easy and quick to put files on it too
