It isn't his business accumen or presentation skills that people miss. It is his ability to inspire people to do better. His passion for doing something amazing.
In many ways John Lennon was the same. Read a biography of him and listen to outtakes from Beatles recordings to see what I mean.
Imagine if we all had that kind of passion and devotion to being and creating the best. Imagine if we all created such amazing things that Steve Jobs and John Lennon looked... normal.
Or going to the bathroom, driving their cars, sleeping... For example, I've only seen the Godfather once. My electric toothbrush, on the other hand? I use that every day! Take that Coppola!
I think Jobs himself proved that software isn't art, and "hackers" are not artistes. I submit the following conjecture: The complaints about the app store approval process would be nothing compared to the shitstorm if Apple started blocking songs and films from iTunes. Remember, Jobs is the one who, if he had gotten his way, would make all software go through a central committee before you could use it. ¡Viva la Revolución! Also, eff the Beatles. Put on some Wilson Pickett or Motown, or your pick of their better contemporaries.
