I don't think you can realistically quantify whatever it is that goes on in the mind of Steve Jobs that sets him apart. Apple fired him and later took him back. I recently read an article which described that to the effect of "he launched Apple twice". It seems to me the words "genius" and "genie" are related and likely this is because whatever goes on inside the minds of some people is so brilliant it might as well be magic to the rest of us. He has something in him that no one else can quite grasp or replicate, some unique combination of knowledge, experience, thought process, perspective and god-knows-what-else which adds up to something that other people simply cannot understand much less do. You can analyze it to death all you want and it won't change it: Other people still won't be able to do whatever it is he does that made Apple what it is.

Not to say analysis has no value. Good, solid analysis has potential to help other people do better. But there is a reason for what this article is calling "the Eureka Myth" and basically some people cannot be entirely demystified, try as we might, even though they may be fully cooperative and making no attempt to "hide" anything.
