IOW, the faithful will in the not too distant future will be able to prove their loyalty with their wallets, forever and ever, world without end, amen. We'll see how that works out. It won't take all that long until you have paid much more for your Windows machine than that stupid hipster and his "overpriced" Mac.
I'm quite sure Windows isn't going anywhere for at least the next quarter-century, especially in business computing. We've had alternatives now for ages, but they just don't get any adoption. Customers have proven, over and over, that they simply will not abandon MS Windows and Office, no matter what, even when they're forced into using a horrible, tablet-ified, spyware and ad-laden version of it.
This isn't like the NFL; no one *needs* to watch sports, it's purely entertainment, and tastes change. Computing is different; businesses aren't going to go back to doing everything on paper, or back to 1970s mainframes. At this point, MS would really have to shoot themselves in the head (not the foot) to get businesses to abandon them. It's just too easy for them to pay the licensing costs and deal with the problems and stick with Windows than to explore alternatives.
