Re #1: Yes, maybe I could get the main use cases to approximate OS X well. But (a) I don't want to learn how multiple windowing systems work and how to script them, and (b) then to fine tune them so corner cases are covered: how to integrate Gnome and KDE applications so their menu bars have the same shortcuts for the same operations, use the same font, have the same DPI scaling, etc... It's a never-ending set of options to fiddle with, little cohesive documentation, and no objective criteria to decide when they've been fiddled enough. Not saying it's a fault of Linux, but that's what we get in a open source ecosystem where the kernel team doesn't dictate how the desktop works.
