Steve Jobs' biography doesn't pull any punches when it comes to Microsoft and is CEO Steve Ballmer.
The New York Times has posted an excerpt which makes it pretty clear what Jobs thought of Microsoft and its CEO:
"In the final pages of the book, written in Mr. Jobs's own words, he described Microsoft as "mostly irrelevant" and said companies like it often ran aground when they were run by salespeople. He singled out Apple's former chief executive, John Sculley, and Microsoft's chief executive, Steve Ballmer, as examples, adding that he didn't think Microsoft would change as long as Ballmer was in charge."
Jobs also told President Obama that he would be a one-term president, that Google copied the iPhone and that he would spend his "last dying breath" and all of Apple's cash to "right this wrong," that Intels' mobile chips were "just really slow," and that he he wasn't a fan of Fox News and thought it hurt the country.
