Having had to deal with Jobs, I would like to say the man was a bit of a mercurial douche trading off his reputation. That being said... he had a great ability to see what computers could be for "normal people." Instead of stealing ideas from IBM or DEC, he "stole" ideas and staff from PARC (who stole some of the staff away from SRI.) Dude was a dick, but he used his dickishness to "encourage" people in the Apple org to make products that were better than they really had to be. [1]
Tim Cook is an amazing operations guy and only sorta gets the product vision thing. Maybe 650 milli-jobs. [2] But the people in the Apple org who have a gut feeling for what makes a decent product from a customer perspective are lower on the org chart. I'm sure they're doing daily battle with the accountants who know the price of everything but the cost of nothing.
[1] Someday I am going to write a memoir about what it was like to partner with NeXT in the early 90s.
[2] A milli-jobs is a unit of product vision. 1000 mJobs is Steve Jobs. 650 mJobs is Tim Cook. 100 mJobs is Gil Amelio.
