Technology That You Loved from the 70/80/90's?

modi123 asks: "I was spending a large chunk last weekend watching VH1's I love the 80's: Strikes Back with a couple of friends. We would comment and laugh at all the dreadful things we were into, and then the topic shifted towards old tech and gadgets from then. I brought up my old 486 Packard Bell (DOS 6.0, Windows 3.1, Doom, all for $3700.00), and it spiraled out from there. The usual things cropped up: Nintendos, Sega Master Systems, Apple II Gs, and so forth. Then it delved into more weird items: Rob The Nintendo Playing Robot, HyperCard, cell phones with 50 lb batteries, and the pager craze. I am curious what the /. community remembers as their favorite technology from previous decades (be it 70's, 80's or 90's). Perhaps we can even chart a timeline if people toss in when they first remember it."
