To this day it surprises me how little the average person knows about technology. They know much more than a decade ago but it is still minute.
EDIT: As a personal example, I have a kid sister, 13 years younger, who is in her third year at Cornell studying law and just had intern job at Google this summer in which she wrote a Google student blog post (Yes, I am very proud). She didn't know how to right-click using her Macbook. She can type like the wind and knows the features of every phone but she wan't aware of tapping two fingers on her trackpad.
To me this is very representative of the average user today. They know enough to get by but don't have the depth of knowledge when it comes to the details. If they read a patent story I don't believe they would understand what they were reading unless there was a perceived gain to it.
In my situation, I explored what my computer could do. She did not because she wasn't interested in opening System Preferences to see the options. Most people won't. The computer is merely a means to an end. Further than that, they're no longer interested. This is why, I believe, that the iPad (or other tablets)is so important but that is another story for another day.
