Apple first introduced its iconic white iPod in the fall of 2001, then gave it the technology buddy it needed — the iTunes store — in the spring of 2003, which was when I bought my first iPod. It was heavy, a third-generation unit with a built-in spinning hard drive and four buttons across the middle, and it irrevocably changed the way I consumed and listened to music. Instead of buying just a handful of choice CDs each year, I bought more songs from more artists, and I was a far happier consumer.
