It's pretty interesting to look back on what was cutting edge technology over the decades. Even more interesting to me how some schools remained behind in terms of not having access to some of these items until years after their introduction.

Even today there are many schools in the United States that do not have reliable access to wireless internet coverage, laptops, or mobile devices.
