I use only XP at work and only Mac OSX at home. I've used both Windows and Mac for many years. I don't have a chip on my shoulder. I'm just explaining my choice.
I use plenty of systems, including the three main types. My least favorite by far is my Ubuntu system. I don’t care much for many BSD systems. I’ve never had a problem with Windows. I don’t seek out these sorts of dicussions, but it seems all too often people are interested in proving what they use is superior. I generally respond to that.
