In the past fifteen years, we have seen Microsoft go from being an unstoppable force to being a non-factor in many important new markets, we have seen Google go from being an unstoppable force to being a non-factor in many imporant new markets, and I suspect we are going to see Facebook struggle with the same thing. RIM is dying quickly now. Yahoo! is a question mark. In technology the more things change, the more the stay the same. You cannot ever rest. Because the big change that is going to upset your nice apple cart is right around the corner. Today that is mobile. Tomorrow, who knows? I am trying like hell to figure out what that will be and jump on it. Because that’s how you play this game.
