Great marketing cannot sell a pedestrian product very well.
Marketing strategy is a series of integrated actions leading to a sustainable competitive advantage.
Steve [Jobs] and I spent months getting to know each other before I joined Apple. He had no exposure to marketing other than what he picked up on his own. This is sort of typical of Steve. When he knows something is going to be important, he tries to absorb as much as he possibly can.
Marketing is really theater. It's like staging a performance.
My guess is that Apple won't just pass Microsoft in market capitalization, but will go way beyond it.
