This is in no way intended to start a Windows vs. OS X vs. other OS battle, but I thought the graph in the article was interesting... Oops, Windows XP gains in January but so does Windows 8.1 TL;DR XP is still used on around 25% of computers, but Windows 8/8.1 is making gains. Mavericks accounts for around 3.2%... So the graph in the article separates the various Windows OSes going back to XP, but it only shows Mavericks for OS X followed by linux and an "other" category. But I know there are still a number of Mac users that use older versions of OS X and perhaps even older versions than that. Can we assume that Mac OS is likely larger than 3.2%? Discuss (namely because I don't want to be that Apple troll on a Windows article on Cnet... lol...)!
