I really don't understand all the hate for windows 8, I've had zero problems running it. I've tried all the start menu replacements and every time I've gone back to using the start screen. Why? Because I find it faster and more efficient...my system flies along and is the best it's ever been.
I had to use my brothers computer last week to install some things and sort a few problems out that he had. He was running windows 7, and I could not believe how awkward it felt. Everything seemed more hard work to get things done, and file explorer is next to useless... I actually missed the ribbon! lol
I tried Linux once, and again I found it too much hard work just to be able to get the simplest task done. I very much doubt the masses would convert to it, not unless they make things easier.
