Okay so I recently got an iPod Classic 80 gb. When I go into, say music, my wheel does not sense my touch for 2-3 seconds, and when it finally does, it lags, and jumps from, say number 2-4, not as smooth as my old iPods. It goes smoother after a while though, but it feels kind of cracky. Anyone experienced it, should I contact apple or just leave it be? It IS pretty annoying.
