Hi, I'm thinking of buying an iPod but can't quite decide whether to get the 30 or 60 gig version. My iTunes library is around 20 GB on a 60 GB hard drive. Is it possible that the size is a bit different on a 30 GB iPod, actually smaller? What makes this decision harder is that I am planning on putting my photo collection on it which is about 5 GB. Anyone can also give a number as to how much space this takes on the iPod? I am not planning on putting the original files on it, but just the ipod sizes, so it should be much smaller, right? I know about the battery advantage with the 60 version... Thanks!
