That said, I personally find vanilla GNOME pretty easy to use. It only took me a day or so to get used to not having things like a taskbar. If you use the hot corner (which is also hated), you can switch to any open app with one mouse click just like with a taskbar.
So either I'm an alien, or people are more adaptable than they give themselves credit for, and will go impressive lengths to not adapt (e.g. making a taskbar for a desktop that's perfectly usable without one).
