Photos: iPod through the years

4.0 by 2.4 by 0.72 inches
6.5 ounces
10GB/$399
20GB/$499
Looking back: I kind of liked the mechanical scrollwheel of the first generation. Still, the Synaptics-aided touch wheel was a technological marvel, and 20GB of storage for only $499--what a deal! Also, Windows users started to buy these things en masse and pair them with Musicmatch, helping Apple gain a solid hold on the MP3 player market. --CNET's James Kim
