who else is getting the 4 gig? I don't think i will fill up 4 gig, because mainly i'll carry about 100-200 songs on it at a time (iPod has whole library).
8 gig - i already have my iTunes playlist and the music on that alone is just over 4 gigs - no way 4gigs for music, videos, pics and email etc will be enough! i wish i could have more than 8!
