Linux

That helps, but switching to Linux often is much broader in scope than just the OS. People have time and money invested in software that doesn’t work in Linux. For example, it’s not trivial to switch from Photoshop to Gimp or Krita. In my case, I detest Windows and have many years of experience with Linux, but still begrudgingly dual boot to use Cubase because I haven’t gotten around to learning something that does work on Linux like Reaper. I also have expensive mocap software that only works on Windows, in addition to using MetaHuman Animator in Unreal Engine that still does not support Linux. I’ll probably get around to getting completely off Windows at some point, but even for me who is a die-hard Linux enthusiast, I have to prioritize my limited free time, so I can see where someone who isn’t would be like meh, I’ll just use Windows for now and not bother dual booting.

I also haven’t been successful getting my spouse to switch to Linux, who has only ever used Macs and thinks everything else is overly complicated. My father uses an iPad and a Windows machine for specialized software that won’t work on Linux and has zero interest in dual booting. My kid, on the other hand, has only ever used Linux and has no desire to use anything else.
