I was very much into BBSs. Never AOL, although CIS. 30 years ago? I don't think I had an Internet connection though. (Had been barely exposed to it in school in the late 70s.) Got things like competitive spec information as a product manager from requesting it from analysts we paid a lot of money to for faxing us data sheets. Pricing info was very fragmentary. There were cell phones--barely--not sure when I got my first one as a rarely-used backup device.
A mobile almost always connected world might have been something I might have imagined in some form as futurology but would probably have take different forms. See Pournelle's version of not-Wikipedia in Oath of Fealty for example.
My local university had a free dialup number that you could use to telnet into anything on that supported telnet. There were a few BBSes on the internet, but I didn't know how to do anything with it. 29 years and 6 months ago I actually went to university for the first time and my dorm had terminals, plus some of my homework actually required that I do things that were on the internet.
The first wifi connected laptops were also coming out at about that time. Nobody thought of phones as for more than voice yet (cell phones did exist, but the cost per minute was very high, and they only supported voice. They also didn't fit in a pocket).
Like I said the ideas were all in place close enough that someone from 30 years ago would recognize everything as the future they imagined - but the details are very different between what they imagined and what the reality turned out to be.
