You sound like someone who hasn't used Windows 8 before, or not for longer than half a day anyways. Windows 8 in desktop mode really isn't any different from Windows 7, except for the fact that the Start menu is now fullscreen instead of a popup menu. Metro a mistake? That might be your opinion, but I fiercely disagree with it.
Just because you don't like Metro, for whatever reason that might be, does not make it a mistake.
I wouldn't say absurd... just different. I mean, if you have been using windows for 14 years and are used to teh Maximize button, and then you use MacOS and click the box button beside the x and.. something COMPLETELY different happens. does that make MacOS absurd? or does that make windows absurd to Mac users? (while proponents of both OS would tell you YES it DOES make it absurd, but they are both WRONG aren't they?) Different isn't necessarily a bad design.
