Jared Newman reported on this gem for Technologizer where he shows how students were given the pros and cons of using the Internet in 1996. I love this con:
Speed — Some Internet activities can take a long time, especially when a lot of other people are using the Internet at the same time.
A lacking infrastructure (on the server end), a 28,800 / 33,600 / 57,600 baud modem and the bonus of a family member picking up the phone. Good times.
