Magnitus: In the advent of a disruption in PC gaming, I don't think Microsoft would drop the ball and Windows will vanish. Most shifts are not that sudden.
I just think another alternative would gradually acquire more mindshares, because it is better.
StingingVelvet: Microsoft's long-term goal is a streaming subscription service that works on any device. Their current support of PC gaming is nice though, and should last for many years as streaming faces many difficulties to get over. Until that point MS wants a platform agnostic subscription service that includes Windows.
The real short-term "threat" from MS is subscription exclusive games, in my opinion. Those will come eventually.
How about this?:
Someone gives you a Linux spinoff that is even easier to use for a layman than Windows and that can run:
- All Linux apps
- All Windows apps (modern or legacy)
- Built-in drivers for some amazing new hardware that they have
And it is free. You wouldn't switch for that?
That's an extreme unlikely case, but there's a whole range of possibilities less extreme than that that would convert a lot of Windows users.
And yes, Microsoft is transitioning the core of its business toward rental (cloud services), not ownership (installed standalone software)
Nowadays, Windows is to Microsoft what GOG is to Cd Projekt Red
