Aside from the comical view of emails in the 1990's, the main idea I got from it was things were still changing as rapid as they are now. People back then may not have been used to emails, but now we are trying to adapt to new developments like cell phones, blogs, chat rooms, etc.
True. I think in like 10 years people will be just as confused and unsure about the blogs and myspaces of today. kind of a steve Irwin thing ..."look how the acient people logged on to their myspaces and talked through comments....GORGEOUS!!"
