I'm running Linux for decades now without problems. Gaming was Windows' last bastion, but SteamOS is looking more and more attractive. So maybe I can get rid of that crapware personally.
Not by a long shot. Windows-only enterprise software (QuickBooks, SolidWorks, etc.) is the last bastion, and that bastion is going to hold for a long time.
Unless they all band together, their capital is not enough to sway Microsoft at all.
But yeah, SolidWorks is notoriously flaky. It doesn't even work OK in a Windows VM. Or on any modern Laptop with discrete GPU.
QuickBooks Online is missing so many features of QuickBooks Enterprise that they probably shouldn't even share the same name. Many places I've consulted for are locked-in to Enterprise.
They also conveniently void your support if you use a VM, despite VMs working fine.
Windows of course doesn't go anywhere and will have a significant market share for decades to come. But Linux has come a long way. I'm not even interested in it, and use it because it's the simplest "just works" OS without having to actively defend against various dark patterns and anti-features.
The experience was so good that a few months ago I tried Bazzite (a "flavor" of Fedora Universal Blue aimed at running Steam games easily) at home as a test and despite my nVidia card (which it really didn't support well until recently) it's been smooth sailing. If it matures a bit more, I may ditch Windows completely... and that was already the last Windows machine at home.
