It was the best question pitched to Apple CEO at WSJD's Live conference: Why was the iPod discontinued? Apparently it's a very simple reason: "We couldn't get the parts any more," explained Tim Cook. "They don't make them any more." While the iPod Classic isn't exactly a creaky transistor radio just yet, that's how it went down. "We would have to make a whole new product.... the engineering work to do that would be massive." The difficult truth that some of you probably don't want to hear: "The number of people who wanted it is very small." So pour one out for the iPod Classic -- and hit up eBay if you're still craving a clickwheel.
