A small number of well-considered UI/UX design schemas really
is a useful thing.
Apple is, generally, good in many particulars. It is extremely conservative, with only two desktop models (Classic Mac, 1984 - 2000, OS X, 2001 - 2019, and ongoing, which is to say, longer than the original interface). It is ultimately completely antithetical to how I work in desktop, and I find myself vastly prefering Linux and the option of selecting a desktop environment. Ironically: Windowmaker, based on the foundations of the OSX Aqua desktop, NextStep.
Increasingly it seems that Apple is stuck with implications of design decisions made decades ago which correspond increasinly poorly to current practices. The high cost of cycling between applications in particular. No, I don't want ALL FLIPPING WINDOWS of an app to pop up when I switch between the primary current working windows of two different apps. Or workspace flipping as I switch / open new app windows.
Apple's third OS UI, iOS, has a tremendous number of shortcomings. As do virtually all other mobile interfaces. I'm coming to the conclusion that any screen size < 10-15 CM is simply too small to be useful, and prefer a minmum 9-10" (20-25 cm) devices myself.
