I agree with the OP that there is a lot of marketing bullcrap that gets around in the form of "whitepapers". But WNT has a sizeable server market share and is growing pretty well, so the OS itself is not trash (http://en.wikipedia.org/wiki/Usage_share_of_operating_system...).
It is still interesting to me how Android doesn't show up on web usage shares whereas iOS does; my website reports far more Android share than iOS (and I'm on Android now).
