I couldn't trade my ipod (5th Gen Video, 60gb) in for any other (well, except an 80gb or 160gb Classic) cos everything else is too small capacity wise, but if I could get a 64gb Touch, I would buy it in a heartbeat! I've borrowed a 16gb touch for the past week from a mate to play with, and it's SUPERB! Such a great bit of kit, but it just doesn't have enough storage! Nor the 32gb!
Course, it would be EXPENSIVE, too expensive for me! Thats why I waited for the 6th Gen to come out before I bought a 5th Gen second hand, which I think I got for about £85?
