Communication now is ubiquitous. I was walking down the street this morning and saw a group of kids, perhaps no older than 7, each one armed with and frantically using their mobile phone. It is hard to believe that just a few years ago, communication was much more limited. Technologically, the home telephone was the most exciting, and even when “cordless” they were not exactly the most dynamic way to communicate. Since you were still tethered to the base station in your home.
