The only thing that drives me nuts on a regular basis is the lack of fully functional Microsoft apps. Specifically Teams and Outlook. Unfortunately I work with Microsoft shops constantly and need those two apps. Outlook PWA has issues and freezes constantly. Teams PWA just doesn't do notifications.
That's it.
But Windows blows and Macs are just too damned expensive.
In the same boat. The web versions have compatibility issues with the desktop versions when it comes to formatting. I've resorted to running Windows unlicensed in a VM.
