I'm not saying he didn't save apple or whatever, I'm just unconvinced that being that particular model of arrogance was necessary part of said "saving". Obviously we can't roll back time and replace him with an identical clone with the only difference being that he didn't shout at people or have personal vendettas against other people.
I don't recall similar stories about Bill Gates, and yet MS clearly did well.
He was, unquestionably, a true visionary, though, and his obsessive, brutal management style, allowed him to implement his visions, with little interference. It reminds me of the "bad guy" in Braveheart, Edward "Longshanks" the First. He was a complete bastard, but he also unified a lot of what is now Britain.
Steve Jobs was also an outstanding persuasive speaker. He could not only convince you that the world was flat, but sell you First Class tickets, on a boat to the edge. The "RDF" was real.
But so many people think that dressing, and acting, like Steve Jobs will somehow allow them to channel him (see: "Cargo Cult"). They get the "asshole" part down, but can't quite synthesize the "visionary" part.
It's a bit ironic that Tim Cook is sort of the polar opposite of Jobs. It seems to me, that he's actually a rather decent chap (as much as any CEO can be).
I don't know about yelling and vendettas, but he has a checkered relationship with the open source/hobbyist community because he imposed proprietary licensing on his BASIC implementation despite the computer hobbyists of the time working more on a FOSS model. When hobbyists copied his software despite the license, he wrote an open letter claiming they were stealing from him. However, the rampant copying also meant Microsoft Basic became the most popular variant which solidified Microsoft's market lead.
Business people, startup people, VC funders, etc all idolize a specific image of Jobs, which mostly appears to focus on how he dressed, and how he was an asshole to people.
We will never know if being an asshole was needed to get Apple to where he got it, I'm inclined to think it isn't.
