As an 41 year old, I’ve actually used rotary phones and classic handsets when I was younger. And damn do I miss them. There was a distinct enjoyment in being able to properly slam down a phone when you wanted to make a point. Same thing with flip phones: you KNEW when someone hung up in a huff. Can’t quite get that point across on a smartphone.
I also miss being able to properly shoulder a handset to keep your hands free.
