However, there are number of inexpensive (under $10) and free utilities that fixes the interface so that you boot to the desktop and never see it. But... most consumers wouldn't be smart enough to know this. They were forced to use the new UI.
I'm smart enough to know it, but dumb enough not to bother. I'm not an extensive UI customizer (outside of when using Linux and a tiling window manager) - you dance with the date you brought. If I'm on a Mac, I use it like a Mac because that's how all apps, settings, and utilities expect you to use it. Why fight against the current? I'll use the keyboard prefs to put the control key in the right place, but other than that, OK, today I'm a Mac user.
Same with Windows. Sure, I could install a shell that works the way I'm used to everywhere else. But that's struggling against The One True (Terrible) Way and seems futile. Worse, it means I'll only be proficient on that one particular computer, and somewhat lost when using someone else's. When in Windows, I do as the Windows does.
You can know all about the alternative interfaces and still not choose to use them. Personally, I just adopted the approach of not using Windows at all, ever, unless I absolutely have to. It's served me pretty well so far.
