i currently have an 80gb 5.5 gen ipod and i love it to bits. its fast and responsive, plays without any problems, and generally runs like a dream for me. im running out of space though and, considering how cheap the new classics are, im thinking of upgrading and replacing it. question is, do i get a 160gb one or 120gb one? i wanted to get the 160gb one for two reasons: color and space. the 160gb one is "blacker" than the 120gb one, right? plus i want the comfort of having that much space in my pocket. don't mind it being a little bit chunkier either. however, i read that the 160gb one can be a bit slow because it has 2 hard drives (or 2 disc platters?). i've seen videos too which show that the 160gb lags a LOT behind the 5.5 gen one that i currently have. plus, its a bit harder to find for me seeing as it has been discontinued. so im also considering just picking up the 120gb one if there's a trade off in speed. any advice?
