While that's true, Apple grew to have a wide variety of products during Jobs' tenure as well. In 2007 there was the iPod Nano, Touch, Shuffle, and Classic, for example.

So it may be that different times call for different strategies. Perhaps the lesson is that you should focus intensely in the beginning and ship varieties once the product has reached a certain level of maturity?

I'm not in a place to say, but sometimes I wonder if we could go back in time and replay "Apple with Steve Jobs" while believing Steve Jobs to dead how often we would say, "Steve Jobs must be rolling over in his grave."
