Seventy-seven percent of middle-age Americans (35-54 years old) say they want to return to a time before society was “plugged in,” meaning a time before there was widespread internet and cell phone usage. As told by a new Harris Poll (via Fast Company), 63% of younger folks (18-34 years old) were also keen on returning to a pre-plugged-in world, despite that being a world they largely never had a chance to occupy.
Mobile phones were widespread well before smartphones were invented.
I mean it is a pretty brief time period to be nostalgic over. In USA, any cellphone ownership passed 80% in 2010. That is an overall number. Depending on who and where you are it might have been before or after. I think 80% is “widespread”. Smartphones passed 80% in 2019. So you are talking about 9 years.

Tbh i do not know if relevant to making/breaking plans because my experience was that as soon as both parties have any kind of mobile device, plans started being more fragile. Not sure if smart/dumb has any impact. Maybe i misunderstood your point…
