Jobs, for all his enormous character flaws, was a humanist - he believed in people and he wanted to make beautiful objects that would enhance people's lives. He was also an enormous asshole and constitutionally incapable of masking his disdain for solutions he didn't feel measured up. Ive can make a visually beautiful object, but he's shown he doesn't have the feel for the actual user, and Jobs' humanism is the half of that partnership that made it work.

Altman's got none of that (well, except the asshole part) - no vision, no taste, no concept of what a user would want, no real belief in humanity or desire to make things for humans. Ive and Altman together is going to be a disaster.
