Is there a sound quality difference between the I-pod 2nd generation and 5th/6th generation? My ole' I-pod Nano 2nd generation is only 2 gigs and filled up. I really like the wheel instead of the touch screen, so I am thinking of just picking up a 5th gen I-pod nano 8/16 gig.
Just was not sure if I would get better quality out of a 5th/6th generation Ipod from the older 2nd generation.
