Over the past year I've (for the first time) used Mac OS X on my laptop, I find it much less useful, and frankly much less user friendly, than Gnome 3 (and even Gnome 3 hides too much information because it assumes its users are technophobes).
One can understand Microsoft and Apple designing user interfaces primarily for technophobes, because in the modern world the majority of their users are people for whom the full power of a computer system is too complex for them to understand, much less use; and, seeing that they have in effect a duopoly, the fact that their more technically able users are not well served by their user interfaces doesn't matter, because there aren't enough of us to be a significant market, and most of us will be told what to use at work in any case.
But I really don't understand the Gnome designers' reasons for hiding so much, for making even moderately technical things so awkward. In practice, almost everyone who chooses to use Gnome is a geek. Having said that, if it really annoyed me I could either switch to something else or get under the hood and modify it, and I don't.
For me, Gnome 3 works with niggles. MacOs X is really annoying, but I can use it. Windows 7 is tolerable. Windows 10? Just let's not go there.
