That you can buy a non-Windows computer or device and still do most of the things anyone cares about doing on a computer is exactly what Microsoft didn't want to happen. Now they are competing on a level field, and not losing ground too fast, but their reign of total domination of personal computing is over.
In the sense that Microsoft is no longer paid that much attention to. There was a time when Microsoft was feared, hated, and begrudgingly respected. Now? They're like an aging uncle who was once a celebrity rock star but whose prime has long since past, even if he refuses to recognize it. Sure, you still hear his songs occasionally, but they're on oldies stations.
Sure, they lost their lock-in, but everything else is pretty much the same.
