OK. So I got my 12" iBook in July for University and since then I've done a very good job of filling it up with music. Now my itunes library is 19.12gb, not much to some, but quite a lot when the hard disk is only 60gb. I'm guessing that my only option is to get an external drive, so I was wondering if anyone could give me any recommendations? I'm an impoverished student so cost would be the main thing. Portability is not really an issue as I have my shiny new iPod shuffle to tide me over if i'm away from my iBook. Does anyone have any experience with using an external drive for their music with success? I don't want horror stories! cheers for any help.
