Alright, I have a dilemma about which iPod to get. I currently have a 31GB music collection that is constantly growing. Unfortunately, my 1st gen ipod video is only 30GB Because of the size of my library, the ipod touch is out of the question. So that leaves the ipod classic. My question is: Should I get a 120GB classic, a (used) 180GB classic, or should I hold out until the next rev (if any) of the classic is released? What do you guys think?
