>"Sure... switch to *Nix. Except my video project files are all Vegas"
There are always cases where someone uses proprietary software applications that aren't going to run on a different platform. However, video editing is possible under Linux with several systems, and they can import existing footage (but not a project). No OS/app switch is without some amount of pain, adjustment, relearning.
>"all my office document files are Office 2016 (I know about Libre... tried it, it mangled the formatting)"
It is unlikely LibreOffice "mangled the formatting" and more likely the documents were poorly formatted or has different fonts that were not installed. MS-Office files can look/wrap different even from one system using MS-Office to another using MS-Office, or from version of MS-Office to another.
>"I can run my games in a VM and live with the performance hit."
I am not a gamer, but it seems most are now using Steam, which supposedly not only runs very well under Linux, it is often considerably faster. There will be some games that have issues, most specifically those with incompatible anti-cheat. But the situation has apparently changed significantly more positive since even a few years ago.
>"And, if I have a problem, I can search 500 forums for a solution."
As if nobody ever has problems in MS-Windows and has to search online for answers? All my systems have run Linux for decades. I guarantee you if I tried to switch to MS-Windows, I would be online searching lots of things trying to fix/understand.
>"Sure, the user is in "more control" of everything, but a lot of users aren't people I'd want to give 'admin' permissions to... they'd be more likely to delete their harddrive than download a malware scanner."
No doubt there. With more freedom, choice, and power, comes new possibilities for things to go wrong. Never wrote it was for everyone or every purpose. I just wrote that with MS's recent hostilities, it is no wonder more people are leaving MS-Windows. MS apparently continues to loath its customers with more and more force.
