I don't think I'll ever understand this. Unless you own shares, one company's success over another isn't really anything worth celebrating. This isn't a good vs. evil situation no matter how much some people want to paint it that way. 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.
If you're an OS X user it is worth celebrating. Increased market share means more companies start paying attention to OS X which means more games, more software, better support and more employers starting to support/allow Macs.
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.
