if apple was to release their macosx to be run on pc hardware then i bet windows would be forgotten soon, but i don't see that happening anytime soon lol my fav os is bsd, freebsd to be precise but it lacks drivers, linux is better with drivers but still not where windows is, i like playing games so i dual boot debian/win7.. imo windows 7 is best windows so far, i used windows xp since 2003 to 2007 i think, it worked well on my old pc but since i bought new one it didn't work as expected.. no problems with win7, had maybe 3 bsod's since i started using it, 2-3 years ago macosx has usability of windows and security of unix, it is certified UNIX os
