Somehow your notes about global menus and kernel update were not there when I first replied .. either a late edit or a network glitch of some sort. Re: global menus, as I mentioned, I'm well aware of the original Apple studies. I admit I'm a power user, but many professional (not necessarily power) users these days have more than one app open on the screen, and I've observed the pattern of "click app to get the right menu, then locate menu item" with a few co-workers -- whereas on Windows (and linux), they only have to locate the menu inside the right window. When Apple did their tests, they focused on use in a single app, IIRC -- which, back then, was justified. That's why I wonder if anyone repeated that with a modern workload. Re kernel updates: No, it isn't great that it can be done in under an hour. I often install ubuntu or debian from a very old DVD, and then, within just a few minutes, it is all up-to-date, kernel and all. Never failed once. I haven't used dnf or yum in a while, so can't comment; I know window breaks. But debian-stable is rock solid, and even ubuntu is (with the exception of the OOM kernel that did byte -- but still took just 5 minutes to update, and left you a copy of the older kernel to boot to if you wanted - which, once you got bitten by the oom bug, you obviously did). I agree Apple updates are miraculous if you are coming from Windows. But compared to debian ... not so much.
