I guess the real message is: believe whatever the mainstream audience believes at the time. You can't really go wrong with always agreeing with whatever the current thought bubble agrees with - and be quick to change your opinions if the herd is moving. When the author saw the derision against Steve Ballmer, and the favor Apple was getting, he made the clear choice to jump ship. And because he was part of that popular herd jumping ship, it worked very well. Follow the wind.
It's actually a pretty good point and is a decent way to always remain relevant. You can't be left behind if you're always on top of the latest thought trends.
EDIT: A missing piece the author points out too: don't be an early adopter of a thought trend (Point 1: Forget the hype). Only jump in when it becomes mainstream. If you adopt something before it becomes mainstream, there's a chance it can fail. If you wait until it is mainstream, but get in just as it becomes mainstream, you get the benefit of being an early adopter and the benefit of never being on the unpopular viewpoint.
