I think Steve Jobs was good at two things. One: he would really push the 'keep it simple, stupid' philosophy on the hardware and software engineers at Apple computers. Computer hardware that was simple to set up, operating systems that didn't require a manual to understand. The original iOS was one or two layers deep when it comes to menu systems.

The second thing he was good at, was being a pitch man. Meaning that he could almost sell anyone on anything.
I think Apple brought a lot of conveniences to the home computer and phone market that were adopted by other tech companies. No I am not crediting Apple for creating the home computer, or the OS. Xerox PARC was a great innovator in a lot of this tech and concepts. IBM innovated a lot of stuff. Microsoft could bring together engineers to inviolate a lot of things. But Apple was good at bring convinces to the computer and later phone world. But unfortunately it was always at a premium price tag.
Throughout most of the 1980's, 90's and early 00's, Steve Jobs and many other tech oriented people were obsessed with bringing Alan Kay's Dynabook concept into fruition. The Dynabook was conceived all the way back in 1972 at Xerox PARC. Apples first real attempt at creating a Dynabook was the Apple Newton in 1992. Steve Jobs considered the iPAD to be a fleshed out version of the Dynabook. Lots of computer companies were working towards this...
