Currently, the main function of the iPod is to play mp3s. There are other features, such as a hidden game, the ability to store phone numbers, etc. But as MacOsRumors has listed before the iPod has incredible potential. Just being able to store music means that the iPod is going to have many other capabilities soon.
But I would still call it an mp3 player, so that I can hypnotize those at my classes who use PCs and have never heard of Incubus!
I would recommend getting an iPod if you really have the urge to listen to music. If you do not have a whole bunch of songs that you want to store, get a 5GB model. If you really want to cram stuff in it, get a 10GB model.
As for problems, I have noticed just a few. First, the iPod has a 16 or 24MB RAM chip that is used to play music directly, once the Hard Drive sends the music data to the RAM chip (I am pretty sure it is 16MB). This is easier because it would waste battery power every time you wanted to hear a song going to the iPod. The problem is trying to keep the iPod still when the Hard Drive is spinning and is carrying music data. If you suddenly jerk the iPod, information will be lost, but you can retrieve it again.
Second, get the latest edition of the software for the iPod, version 1.1 if you can.
Third, if you would like, since the iPod scratches so easily, I would recommend carrying the iPod carefully, or just get a cover. Either should protect the iPod just fine.

The best of luck on the purchase, Paolo.
