Do they still have these? Anyway I present it as a curiosity. Maybe they're heroes for sticking relatively closely to objective considerations like how a slider should behave and when to go fullscreen, or maybe it's all their fault for being pretentious and tastefully elegant and dumbing things down with a 1-button mouse in the first place. Maybe it shows a smooth evolution from good intentions, and successful corralling of terrible erratic interface choices (from the dawn of time, i.e. the 80s and 90s) into something logical and standard, through into an inevitable rise of nebulous "user experience" over function. Or maybe it was all nebulous and abstract from the start, and the high point was in the middle, somewhere around 2000, where it went through a phase of nitty-gritty good sense which faded away again, I don't know.
