When I was 3-5, not only was the phone (not
a phone but
the phone) physically attached to the wall, but it had a rotary dial.
I get a bit of a chuckle out of hearing people say "dial (some number)" when they're so young they probably never saw a phone with an actual dial outside of a museum.
My cell phone ringtone is a Western Electric Model 500 ring, and I have one of
these (which is actually the handset design from the 302). One of these days, I have to take that handset out to the mall or something and sit on a bench having a conversation on it ... connected to nothing.
