Have you read his biography by Walter Isaacson? I think there is no doubt in the tech community whatsoever that he was an ass with people, he cheated his own company people, and also his friend Mr. Wozniak. Also, Jony Ive 'considered him' as a friend, but quoting him :
"He [Jobs] will go through a process of looking at my ideas and say, 'That's no good. That's not very good. I like that one,'" Ive told Isaacson. "And later I will be sitting in the audience and he will be talking about it as if it was his idea. I pay maniacal attention to where an idea comes from, and I even keep notebooks filled with my ideas. So it hurts when he takes credit for one of my designs."
The Isaacson bio got quite a lot of stuff wrong - both personal and technical stuff. If you haven't yet, I highly recommend John Siracusa's podcast book review "The Wrong Guy": http://5by5.tv/hypercritical/42 (skip the first 17.5 minutes to get to the review proper.)
