File, software, and hardware compatibility issues are not as bad as they were a decade ago, but they do exist. With that said, getting the two to play nice can take some time. In fact, I myself own a Windows PC as well as a MacBook, and so far one hasn’t killed the other (or me) while I slept. Can you imagine the nerve? In the same household! Yet it does occur. Given the situation, it’s almost unnatural to think that – *gasp* – someone might own both a Windows PC and a Mac.
It’s not uncommon for Mac buyers to become overnight loyalists, but Windows has an entrenched fanboy battalion as well.
Microsoft and Apple have always been competitors on some level, and as a result, their fans often contain a bit of that old competitive spirit.
