@Wayne,
Your totally correct!. Most people dont care how computers work, and they certainly dont want to fix one!. The problem is that they have no choice!. I work with over 100 people who have computers that dont really care about computers. They just want them to work. I'd say that I've had about 75% of the their machines sitting in my living room because there all running windows and so overrun with adware that they can no longer check their email or surf the net.
I dont see this changing anytime soon. If we still had 4/5 equally market shared OS's then maybe this problem wouldnt be so out of control.
