That is not condescension as I am not condescending towards users. Rather, it's reality. I volunteer with an association of retired people and 100% of our executive and every single member I have ever spoken to fits in in that group. They don't do more than that because frankly, they don't particularly like their computers. I also briefly sold computers when I was in University. Over that 18 months, I'd say that 85% of people who needed my help were looking for machines that could do exactly that.
Finally, I really question what kind of Linux distrust you use. With a half decent, consumer focused distribution, I can't imagine how anything could fall to pieces the moment someone colours outside the lines.
