I can remember a few.
My first experience with a:
remote control for a TV. I was about 5 or 6 years old (so 1975 or so) and my aunt and uncle had purchased a new TV. I was amazed by the fact that they could change the channels from the couch with that big square calculator-like looking device. Magic!
microwave oven. I was about 7 or 8. My father worked for Sanyo and brought home what looked to me like a supercharged toaster oven, and in fact, put it where our toaster oven resided in the kitchen, and my English Muffin pizzas were never the same. He was so excited. My parents microwaved half the contents of the fridge that night. My mother would not let my sister or me go anywhere near it. In fact, we weren’t even allowed in the kitchen when she used it for the longest time, and we were never allowed to stand next to it while it was on.
computer. I was 11 or 12. My uncle purchased a TI-99 for my sister and me. I loved it, mostly playing games on it or learning BASIC and running silly programs.
cd player. I was 14. I’d heard about them, and thought they were the neatest thing. Then my father bought one for my sister and me. The first CD I purchased was Bruce Springsteen’s Born In The USA. Shiny!
cell phone. I remember seeing a couple of guys in NYC carrying those big old boxy mobile phones and thinking they must have been super rich or important to have phones that they could take anywhere. I was about 17 or 18.
My first personal experience with a mobile phone was a couple years later when my fiance at the time bought a Porsche that had a car phone in it. Not an entirely mobile phone, since it was anchored inside the car. But it was still fun to call people and say “I’m calling from the car!”
dvd player. A friend of mine had purchased one just a few months after they hit the market. 97ish? He called all his buddies to come over and check it out, raving about the clarity and how cool it was. He had a party, I was completely skeptical until he popped the DVD in (a Die Hard movie, I think.) I became an instant fan and decided I simply must have one. Cost prevented me from owning one until Christmas 2000.
