@bluecastle I bet we are about the same age. I was going to say some of these same things!
Remote control, aka, "The Clicker." I remember when we had to get up and walk over to the TV to change the channel or adjust the volume. Corollary to this... now we have more than 3 channels to choose from, we don't have to wait for a favorite movie to come on once a year (hello, Gone with the Wind and Wizard of Oz), and programming continues all night long; no longer do we hear the Star Spangled Banner at 1AM and then... bzzzzzz....
Word processing. I grew up at a time when we had typewriters, period. If you made a mistake, too bad, so sad. Liquid White-Out was like a miracle, followed up by the White-Out tape. I tried out an old typewriter the other day, just for kicks. Man, you really had to hit those keys hard, and remember carriage return? Now I have a laptop, barely have to touch the keys, can make instantaneously corrections... I love using Word!
Christmas lights where, if one bulb burns out, the rest stay lit. When I was a kid, if a string of lights went out you had to find a new bulb and try it in the string, socket by socket, until you replaced the burned out bulb and the string lit up again. Such a chore, especially when you were SOOOOO excited to be decorating the tree! Also, now-a-days, the tree stays beautifully lit, even when one bulb burns out!
I'm telling ya... it's the little things, some days, that make all the difference!
