Short answer: Enterprise bullshit and Adobe.
On the home computing side, I can’t think of much that has specific OS requirements besides gaming and DRM’d 4K streaming. For better or worse, most desktop apps nowadays are glorified web sites. It’s a different world today than it was 20 years ago.
On the enterprise side, nah. Way too many vendors with either no Linux support or shitty Linux support.
Microsoft is working hard to shove “New Outlook” down everyone’s throats despite still not having feature parity with old Outlook. Nobody in my company will want to use it until it is forced because we need delegated and shared calendars to actually work. And then there’s the “you can take my 80GB .pst files when you pry them from my cold dead hands” crowd. Advanced Excel users are not happy with the web version either, and I don’t blame them.
