Hey, I am gonna buy a mac and ipod some time in the next couple of weeks and while im sorted on which mac to buy (12in powerbook), im unsure of which ipod to buy. My music collection is pretty large (about 175 albums), and i want to have some space to grow. So will 20 gigs be enough? Also, i am unsure at what bit rate i should record at, because i'm a bit of a music geek and like my tunes to sound as they should!!!! i question 128kbps because i found listening to mp3's ripped at this quality to be inferior to the CD they were ripped from. so what quality would be best for CD or almost CD quality, and so, which ipod would be best for me? Thanks for any help you can give!
