I absolutely love mine. I can carry all of my music with me. I use it almost every day.
Definitely expensive, though. I was given mine as a graduation gift... Im not sure I would have bought it otherwise (probably though
).
The reason I chose the iPod over the Zen or anything else was size. You can't really fit any of the other players in your pocket quite like you can the iPod. Im convinced thats one of the reasons I use it so much.
