Has Microsoft ever produced a good version 1? Maybe XBox? I don't know much about games. But for the most part I think what MS is good at is slowly improving a turd until it's really quite nice. DOS, Windows, IE, Office, and Visual Studio were all much worse than their competition initially, but successful by their fourth versions or so. But I don't know if MS has the heart anymore to go through a few rounds of failure to reach success.
