Only true if those inconsistencies actually matter to your workflow. Not going to deny that they exist, obviously, but their impact is largely overplayed (and gratuitously downplayed on Windows, in my experience).
Spoken like a true Windows UX aficionado. Who doesn't love multiple system settings apps, a mix of minimal new context menus and overcrowded legacy context menus just one more click away.
Not up close due to the vast number of inconsistencies.
This could only be fixed by a user experience built from the ground up by a single company.
