I personally only use Linux now for all my computers. I follow a philosophy for any software solutiom I need that goes like this:
Use a FOSS solution or,
Use a proprietary solution that has a native Linux build/browser version or,
Use a cracked/pirated version in Wine/Windows VM.
Personally, I am absolutely committed to no more Windows for my personal computing, I have been for years. That means that if I cannot do one of those three options in that order, I don’t use that software/solution.
Unless you are doing a lot of specialized software work, those three options should have you covered. I’m curious what software you use that doesn’t work with any of those 3 categories.
Advanced CAD/CAM stuff there isn’t much in FOSS. Same with specialized Audio production work and advanced photo-manipulation. Specialized device support can be spotty too, but that varies wildly. Those are the only software categories off the top of my head that I know don’t really have good FOSS solutions.
