"There are the less obvious intrusion cases: Why is it that consumers don't lift their fingers knowing full well that certain, apparently legitimate, entities can place code on the PC without having to prompt?. By doing so the property, in this case the PC, is unknowingly altered and, in the best case, slowed performance is the result. Of course I am referring to SPYWARE."
Awk I think there are many pc/internet users who do not understand in a technological or personal way just how vulnerable they are.
Take a look at this pdf file "Georgetown Privacy Policy Survey"(Wave was a sponsor). Is the typical consumer aware of the kind of information about them that is being pilfered from their surfing? Doubtful. Much less so about their vulnerability to spyware....that's just for the movies afterall! <g>
