I had a lot of "oh wow" moments at the end of the 90's and beginning of the 00's with Flash.
A lot of users did, too. But it was usually along the lines of "Oh, wow. This page has flash. Well, I guess I'll go get a Coke while the Flash plugin loads into the browser and my computer can't go anything else. If I'm lucky, the whole thing won't crash and take all my work with it by the time I get back."
We romanticize the past.
