The "Apple comps are the best because they don't get hacked!" stuff is hilarious. And even Apple itself tries to profit on it in their ads. The truth is, though, that Apple is just as easy to hack as anything else. People don't because it's not worth their time. When you want to do the most damage (whatever you want to term as damage), you choose the vehicle that the most people use. And that's Windows.
So the reality is more like, "Apple is the best because so few people use it, people can't be bothered hacking us very often!" And don't forget that the vast majority of people who own an Apple also own a Windows PC. But they won't openly admit that, either.
Regarding the bold . . . what? I think most Apple fans owned PCs before owning a Mac. I still have my PC . . . but it's packed away in my closet. The only time I think about it is when I have to move it.
If anything, doesn't having a PC and a Mac give the people who love Macs more credibility? More so than say . . . hating Macs when you don't own one?
Plus regardless of the reasoning, not having to worry about viruses is awesome. No anti-virus subscriptions, no spyware, no adware. (I secretly hope Macs don't become popular enough that the Mac OS is targeted. However, the popularity of Macs among students might hint at a swing in the market. Dang.)
