Duplex means the sound travels back and forth; half duplex means
push-to-talk (at which moment the other party is silenced)?

Interesting analysis, thank you. It is certainly true for me that cell
phone conversations, and cell phone users, are particularly annoying.

I have noticed however that the most ubiqutous users--the students at
the state university which is my downtown--are much better than adults
on the streets of say New York. Perhaps because they have grown up
with the thang, so they know not to shout? Certainly I have never
heard a student say, as I heard a presumably high-paid businessman
boast as we were settling into a jet liner at Washington National
Airport, "Guess where I am?"
