Gather around children, and let me tell you of the days before everyone walked around with a phone in his pocket. When I was little I read a comic strip in the newspaper (do you remember newspapers?) called Dick Tracy. Dick Tracy would talk on his 2-Way Wrist Radio. You knew it was a 2-Way Wrist Radio because there was a little arrow pointing to it telling you. This was the stuff of science fiction. To think you could communicate with someone with a watch like radio. No way.
Later there was Maxwell Smart. The spy from Control who talked into his shoe phone. A bit awkward for sure, but nevertheless a portable phone. He did have to dial it... but still... this was technology only a spy could have.
Today everyone takes phones for granted. Leave home without your phone and you feel nekkid!
Except for me. I still use tin cans with string.
Just call me old fashioned.
