Whenever I think about it, some things really stick out:
Cell phones - hardly anyone I knew had one when I was growing up, and now everyone in my family and all of my friends have one. Even DH and I have one!!
Game systems - my, how they have come along. I have been wanting to play Atari for quite some time as that is what I grew up playing. Then Nintendo came out and it has only gotten better.
Computers - remember the Commodore 64? Had one of those growing up and thought it was the best - my how computers have evolved.
Record players - my how I miss my record player. I had a huge collection of 45's that I would play. I would save my money just to buy a favorite song and then play the snot out of it. I think my mom still has the Smurfs Christmas on record...
Refrigerators without ice/water dispencers - amazing how now refrigerators come with TV's - gimme a break.
I could go on and on. I do notice that alot of kids are indoors more than outside. I was outside all of the time - playing with friends, riding a bike or exploring.
