In my case it's Solidworks, after paying $14,000 for it we are not about to use an alternative in a hurry. Systems like onShape show promise but still lack features we need for day to day use like sheetmetal functions. Tried a VM but it's too clunky and often has issues / crashes, currently I keep a windows laptop just for work. (all my other PCs are fedora).
Solidworks is the main one, I can find reasonable alternatives for just about everything else, it's the one bit of software we just can't toss out.

It will only be a matter of time before Linux is big enough for all the stubborn companies. I guess the smarter companies should move to Linux, first comes, first takes.

I hope so, I find that I really enjoy using a *nix system, it's fun in all kinds of ways that windows can now never be. It's good that it still supports users who are comfortable without a window manager, at any time I can change runlevel and use the system without all that overhead. I could be wrong but I don't think that's possible with ms-dos anymore.
