My daughter carries around a CD notebook with about 50 discs in it nearly every time she goes somewhere for more than a few hours so I thought it's about time I got her an mp3 player. So I'm looking at the iPod line and couldn't help but notice that in terms of storage that the 30 GB version is clearly the best bang-for-the-buck, costing only $50 more than the 4 GB Nano. Size shouldn't be much of a factor 'cause you can't use it while playing field hockey or basketball or softball and she's not into running. With that much storage she could probably put most of her most-often-listened-to CDs in .wav format. She doesn't care about video or pixs but who knows, that may change after she starts using it.

But other than size is there anything I'm overlooking? I've never owned an mp3 player since I have no need for one.
