The iPod Nano's Changing Form

"Perhaps more than any other device in Apple's electronics arsenal, the iPod nano has changed dramatically over the years. Birthed as the iPod Mini, the first generation nano rounded off and slightly shrank the design, while adding a color screen."

This was one change that I really didn't get from yesterday's event. But then again, I think that has been the problem with the Nano all along, just where does it fit in the iPod mix. As you can see from all the various changes, perhaps Apple has been wondering this same thing as it has taken on many forms over the years. What are your thoughts? Do you think the Nano change is good? Bad? Too close to the Shuffle?
