I understand what you're saying about Linux, and it's a great alternative for some people, for others not so much. A properly protected Windows box can be very secure though, and for those users who will surf anywhere and click on anything, using a limited account without admin privileges will stop a lot of problems before they can get started. FWIW, I haven't had anything more annoying than the occasional unwanted toolbar or ad popup on any of my computers, or my wife's and daughter's, in a very long time. I can't figure out how people have all these troubles, myself...
