By 2010, Windows’ fate was sealed. The web and the iPhone had disrupted personal computing, forever pushing the user base---and developers---away from the PC. And so Microsoft was left to decide what to do with Windows. It could coast and let the revenues from businesses roll in while their employees engaged in traditional productivity tasks on increasingly uninteresting and anachronistic hardware. Or it could try to escape the innovator’s dilemma and disrupt its own business, as Steve Jobs had done to the iPod when Apple announced the iPhone.
To its credit, Microsoft chose the latter route. Unfortunately, the man running Windows at the time---Steven Sinofsky---was politically divisive and ill-equipped to take on the role of product visionary. And the decisions he made would go on hurt Microsoft internally and, eventually, externally as well.
