Didn't know where to put this, so I figured it could go here. I'm going to get a 5th generation iPod touch, but don't know if I should get 32 or 64 gigabytes (it's about a $70 difference on Amazon). My total iTunes library is 19.3 gigs, so the only reason for the 64 gigabyte model would be if it were sufficient for some years. Any thoughts? Anyone know if/when the 6th generation will come out?
