I forgot when I first heard about cell phones, but it was a long time ago. I'm old enough to recall, as a kid in the ( late ? ) 1950's, folks walking around with an actual working radio that could fit in their shirt pocket. That transistor technology was mind blowing back then and there were all kinds of futuristic predictions being made.
When I was a teenager, my folks got cell phones, but back then a cell phone was something you had installed into your car, not something you carried around. They gradually transitioned from that to hand held phones about the size of a typical home telephone that you clipped on your belt to carry it around. Then came the flip phones you could put in your pocket. Smart phones made them obsolete.
