Personally, I'm just happy that I can use any of the 3 major OSes these days without a problem, which is largely thanks to FireFox eating IE's marketshare on Windows.
Everything-windows is so commercialized, that even googling for home networking issues will keep landing you onto commercial message boards overloaded with ads and polluted by retards. And every little piece of shit software utility is $9.99 shareware.
10% won't be much of a problem, but I'm quite happy with how things are right now.
5 years ago I predicted that MS would be gone and OS X would be the only widely available user friendly operating system (of course, the various Unix derivatives are going to survive and be healthy, but niche, players for many decades to come.. in fact Mac OS X is built on one of them, Mach 3 Unix, and is dependent on this programmer base for it's depth and stability).
I was obviously wrong in that prediction but "better late than never".
