"Inside Look at Birth of the iPod" shows some of the interesting details about how the iPod project started. As an iPod owner, I think the single best feature is the simple interface. Everyone else (that is, non-iPod owners) are quick to dismiss the iPod, big deal, it's just another player, but they don't realize how much better it really is. Anyway, I enjoyed reading that Steve Jobs was involved with the design, insisting on simple interface rules like being able to find a specific song within 3 button clicks. Sure, there are times when I use 1 or 2 more clicks to find specific songs, but with a music collection of more than 4,500 songs I think 5 clicks is perfectly suitable. I know that the other players out there would be so cumbersome to use that I probably would give up and just listen to something else.
