It was clear to me that there was a phase change when the iTunes store came out - wow, was that 2003? Anyway, the reason I am not rich is because I didn't believe in Steve Jobs, so I didn't have the faith to hold AAPL stock forever. But the iTunes store was the point at which it was clear something spectacular was happening and Apple was moving in to a new world, compared to the days when the WSJ constantly called them "beleaguered".
