What surprises me is how easily people have accepted crap audio on their phones in a trade-off to have a portable swiss-army knife computer in their hands all day. POTS had/has great sound quality in comparison. Calls are clear and you rarely get disconnected. Conference calls anymore just wear me out. I spend most of my listing power just trying to figure out what someone just said on their $600 phone.

Maybe someday it will get better but I haven't seen any improvement in years. IMO just the opposite.
