I've kept Windows only for gaming and specific software, today most software is multiplatform or has a web version, and Steam uses WINE/Proton which makes probably over 90% of my game library playable, and for the rest there has many alternative ways.

It's only been a few weeks, but I don't have Windows installed on any of my PCs now. It's a shame that I still need lots of fiddling to figure out Nvidia drivers and why Wayland is not there yet, so for now I have to use Xorg, but for experienced users, it works really well.

I really wish it could be the same for newbies tough.

Newbies need to buy Linux preinstalled, which is for some reason very hard to find in shops.

True. What we need is a hardware manufacturer that pushes it the way Apple uses their hardware to push Mac OS. Like System76, but bigger.
