Steve Jobs learned to play well with others:

Catmull dedicates a chapter of his superb recent book Creativity, Inc. to what it was like to work with Jobs. Catmull, who has the least overt ego of any senior executive I’ve ever met, saw Jobs mature enormously over time, especially in the development of personal empathy and humility.

I find it fascinating to read this type of articles. As arrogant as Steve Jobs was portrayed to be, I believe that as a CEO he had highly developed communication, collaboration and listening skills. 

The way I see it, accounts of Jobs running the company on his own are highly exaggerated.
