Exactly. Unfortunately, not all of us have the time or interest necessary to learn the ins and outs of keeping a PC in good running order. I shouldn't have to know how to fix my car in order to use it, and apple conveniently takes care of these issues for me. From the fact that things cannot be installed on my computer without my personal password, to the awesome service department known as the genius bar, there is nothing I have to worry about on a daily basis. My last laptop was 2 years old when I stupidly dropped it and cracked the LCD. Other than that though, it was working just as well as the day I bought it. As for the specter of virus overrun macs somewhere in the future, we'll cross that bridge when we come to it, and something tells me that with the genius bar, I still won't have to worry about it.
