Before Toy Story came out, when Ed was not even sure they would even get a film out the door, Jobs started planning the IPO. Catmull disagreed, but Jobs pushed it through, and Pixar IPO'd a month or two after the barn-stomrning success of Pixar. The IPO made Jobs a billionaire, and put pIxar on the finanical footing to its current success.
Jobs knew how to, and took risks that even a fantastic business-builder like Catmull was afraid too.
Its a skill, and a personality that is rare and it built the foundation for two world class businesses on the same IPO. Don't knock him ... too much.
