Having read multiple Jobs biographies, it also seemed to me that he may have been bipolar, but unmedicated because of his stance on medication. Sometimes very hard to work with or be around. People ascribe incredible genius to this guy, but forget that he could be a very impulsive, arrogant and sometimes cruel human being.
Regarding Steve Wozniak, that's another big issue. Not only the betrayal, but it betrays a divide between Jobs and Wozniak. The original Apple II was a computer designed by Wozniak, and very open to tinkerers. Jobs didn't want the computer to be open or to have many extension slots, he wanted total control over the system. He designed his vision of a computer (the Macintosh), and it was a flop. Jobs killed the Apple II and sent the company on a downwards spiral that lasted several years.
It kind of pains me to see that so many people in tech love Apple products, but forget that Apple is not a platform made for creative engineers, it's designed to be a closed system they have control over. They don't really value or encourage your curiosity. They don't want you to peek at what's inside. Even though Apple, like most tech companies, was started by creative engineers.
