In complete honesty, most people are in the same boat as aforementioned sister. My father has a PhD, my twin brother is an architect and my sister is, well she is a photographer, but still these are smart people. One uses a Mac exclusively, one uses MS exclusively, the third uses both, but I am constantly being called to take care of things because they aren't computer people. Just like most people here probably don't even change their own oil, which is actually easier than installing Windows once you get the hang of it. The fact that any software company defaults extra software to be installed betting that the user won't know/think that they don't want or need it isn't right, but unfortunately there isn't anything stopping them. I know for a fact that have never, with one exception, read the entire "Terms of Agreement" of anything I installed. Seriously, who does?
