Yes. I used Windows via BootCamp back in 2008. It was painful, with the fans running full speed all the time and the trackpad not responding in the way it should.
After a few more tries, I gave up. I occasionally used Windows since then through a VM in order to access something specifically, but these days there's nothing left on Windows that I need to use. Office on MacOS is good enough for the light use I put it to. VS Code / JetBrains tools have replaced Visual Studio.
There's no reason for me to use Linux as a desktop vs MacOS. I build Docker containers that run Linux, but that works fine from / in MacOS.
Sadly no. We are pretty much done at that point because we often need Windows specific programs to fulfill grant requirements. I might buy one for myself, but I get the feeling some Higher Ed is done. Government contractors don't really do Macs or cross platform.
