I had a personal computer in 1975. And radio amateurs had a pocketable device he could make phone calls everywhere in Finland. The coverage was probably better than cell-phones today, because at 7 Mhz. I also had internet address in 1985: timonoko@nokia.fi.
Nothing much else has happened in last 30 years.
