You guys hit on a bunch of good things to miss, but there are just as many reasons to be glad the 80s and 90s are history.
Today you can walk into many car dealerships and purchase a car with 400+ hp, if not more, pulls close to 1gs in the corners, gets 30 mpg and doesn't have a bone jarring ride. Try that in the 80s
You can use your cell phone to access the internet and locate, order parts 24/7. Or use it to give you voiced step by step directions on how to get to a location without pulling out one of those bulky, folded-up paper maps and trying to remember each turn. Or call across the country without long distance charges.
And of course, use it to find and post information on the PY forum while sitting on your couch and watching your big, 3d flatscreen.
