OS X gets viruses the same way Windows does, from downloading programs from P2P services. Oh and... I don't have to pay for any of these. Not because I'm pirating them or something, but because I use free ones. I've heard horror stories about them, and that might apply to some that are really malware posing as AV/anti spyware programs, but mine are all proven programs from legitimate security companies. My (free) Antivirus is substantially better than most for-pay ones anyway. Either way, I'm still more secure running Windows + security compared to OS X + nothing. Even assuming that a virus could never break through OS X's magic defenses, that configuration does nothing about tracking cookies or phishing. I know my computer doesn't have any viruses because my antivirus program tell me. Keeping in mind that well made viruses are deigned specifically to hide their presence, How do you know you don't have any viruses? Oh, and if you turn out to be right, and 7 is the end for Microsoft, OS X is going to be the new target. Wait, Ad blocker? I wasn't even aware there were any that wanted you to pay for them. I also fail to see how OS X is any different in that regard. Take a guess what kind of computer I'm posting on right now. It's a 17 inch Mac Book Pro. At the time I bought it, it was the lightest laptop with the specs I wanted, I was interested in trying out a non Microsoft OS, liked the longer battery life, I wanted to be able start from a clean installation rather than one with a bunch of trail software, take your pick. That last one turned out to actually a bit of false advertising, it came with a trial for Aperture. I have had massive problems with XP and vista on this computer. Why? Because it's a Mac, so for running Windows I have to use whatever drivers trickle out of Apple, the black box of the consumer electronic industry. And it's kind of funny that you assume that you know what I use my computer for. I do use it for games, but if that was the only problem I had with OS X, I'd just fire up Crossover and be done with it. No, I find OS X's interface to be almost insufferable for anything that uses a mouse, a keyboard, multiple windows, or is best suited to run in full screen. Specifically, OS X forces an acceleration curve on your mouse pointer. It gives you no option to turn it off. It can be bypassed using USB Overdrive, but that's fixing a problem that shouldn't be there in the first place and disables me from using on-the-fly sensitivity adjustment. That feature sounds like it's just for games, but I get far more use out of it when I'm using Blender or The GIMP. The keyboard is more a problem with Apple's mushy keys, but there's also the irritating way Apple maps all their hotkeys to command. This results in a conflict with numerous programs, and other OS X specific hotkeys. OS X's application focused ui really screws me up when I'm trying to read from one window and type into another window when both those windows are for the same program. You know how I got around this? I installed both Word and Neoffice, and run them at the same time. This would be no problem in windows, because I can just hit Alt+Tab to swap between them, but the same key stroke in OS X can only swap between application, not windows. I can start expose with F11 or something, but I still need the mouse to select the new window, meaning I need to take my hands off the keyboard. Spaces sort of fixed this problem, but it's still a more complex process, and I could still just use Windows and not deal with it at all. OS X doesn't play nice with programs that like screen space. That dock just gets in the way no matter what. I also miss the taskbar... pretty much the entire time I'm using OS X. Instead of using Expose, I can just scan my eyeballs across the row of programs and read what each one is.
