I think this, and the rest of the comments have missed the point, It's not linux or windows really that's going on, but that "computing" for the masses has shrunk down to the browser and Office (or it's clones) - the operating system these days has become marginalized for most people. the File Open dialog is about as far as they interact with it, along with CTRL P and the dock. Linux is perfectly capable of this.

I run linux on my laptop, I run hadoop, a virtualbox for some VM's, a dozen terminal windows spread over two monitors and python. When I go home I have a similar setup on a MBP and most of the time I can't tell one from the other. The operating system, even for development has become quite irrelevant. I havnen't tried windows in decades... have they fixed the C: nonsense yet, or (stupidly) using the wrong slash in file paths!
