Why bother with Windows? Mostly the same reasons moving from Windows to a Mac can be a pain, however on macOS you get better professional software support and less reasons to virtualize Windows from time to time. To be fair, what's the point of using X operating system if some of the tools you need require a virtual machine or you've to use alternatives that are sub-par, will make you waste time and have a worse experience. Again even under macOS with Microsoft's own MS Office for Mac things sometimes aren't as compatible as they should be.
Linux desktop is great, I love it but I don’t sugar coat it nor I’m delusional like most posting about it. Here is a list of cases that aren't easy to deal in Linux:
- People who need the real MS Office because once you have to collaborate with others Open/Libre/OnlyOffice won’t cut it;
- Designers who use Adobe apps that won’t run properly without having a dedicated GPU, passthrough and a some hacky way to get the image back into your main system that will cause noticeable delays;
- People that run old software / games because not even those will run properly on Wine;
- Electrical engineers: Circuit Design Suite (Multisim and Ultiboard) are primarily designed for Windows. Alternatives such as KiCad and EasyEDA may work in some cases but they aren’t great if you’ve to collaborate with others who use Circuit Design Suite;
- Labs that require data acquisition from specialized hardware because companies making that hardware won’t make drivers and software for Linux;
- Architects: AutoCAD isn’t available (not even the limited web version works) and Libre/FreeCAD don’t cut it if you’ve to collaborate with AutoCAD users;
- Developers and sysadmins, because not everyone is using Docker and Github actions to deploy applications to some proprietary cloud solution. Finding a properly working FTP/SFTP/FTPS desktop client (similar WinSCP or Cyberduck) is an impossible task as the ones that exist fail even at basic tasks like dragging and dropping a file.
If one lives in a bubble and doesn’t to collaborate with others then native Linux apps might work and might even deliver a decent workflow. Once collaboration with Windows/Mac users is required then it’s game over – the “alternatives” aren’t just up to it.
Windows licenses are cheap and things work out of the box. Software runs fine, all vendors support whatever you’re trying to do and you’re productive from day zero. Sure, there are annoyances from time to time, but they’re way fewer and simpler to deal with than the hoops you’ve to go through to get a minimal and viable/productive Linux desktop experience. It all comes down to a question of how much time (days? months?) you want to spend fixing things on Linux that simply work out of the box under Windows for a minimal fee. Buy a Windows license and spend the time you would’ve spent dealing with Linux issues doing your actual job and you’ll, most likely, get a better ROI.
Also, the guys take on "what you go for it's entirely your choice" when it comes to DE is total BS. What usually happens is that you'll eventually find out while you can use any DE in fact GNOME will provide a better experience because most applications on Linux are design / depend on its components and installing them on KDE will simply give you small issues here and there, windows that don't pick on your theme or simply create a frankenstein of a system composed by KDE + a bunch of GTK components.
