I always thought of the iPod as THE inflection point for Apple. Not the 1998 iMac, not the iPhone, even though it was the latter that made Apple the company it is today. But I think the iPod put Apple on a track to get to the iPhone-it's why Apple/Jobs were even thinking about it. The pod and the phone shared form factors and have always been intertwined in my mind. For that reason, when the iPhone came out, I automatically assumed that Apple had just killed its iPod business. I was wrong, but I suppose that it did eventually come to pass... 15 years later.
