I think Ballmer at number one makes the list. Anybody trying to make a statement at any point in time about which tech products will be relevant in the future will be hard-pressed to hit better than 50%. Microsoft repeatedly throws good money after bad, chasing the latest fad but never getting any of them completely right or, more importantly, creating any game-changing innovations to speak of. They saw Sony making the PS3 and decided they had to build a competing product and threw away billions in the process. They saw Google, and assumed they needed to build the same search engine to remain relevant. I can't believe that Ballmer has managed to stick around as long as he has, but if I were a Microsoft employee or shareholder, I would want his head to roll.
