I have only been using windows 8.1 for a few weeks with my notebook. I don't know the differences between 8 and 8.1.
My first thought was to install classic shell but I wanted to look at the Windows 8/Metro as it is. It is usable with a mouse (I don't have a touch screen) and for any applications that are not pinned on the taskbar or have a shortcut on the desktop, I have to go to the start screen and down to the applications which is not much trouble. And there are newer and better features than 7. I don't like the new full screen applications (metro applications?) as I cannot resize their windows but everything else seems alright.
The only time I looked for something that I had to type was the "Startup Folder".
I think Windows 8 came too early. If Windows 10 was released before Windows 8, and after people got used to it Windows 8 got released, there wouldn't be too many screaming like the OP.
