Where I'm at, payphones are not only alive and well, they are constantly used and there are sometimes 6 at one particular intersection. Out of those 6 or so, only one has been murdered (someone just beat the fuck out of the receiver and left it with 2 wires coming out, next to a dented Busch beer can)
I would estimate there are at least 50 payphones along the main drag. I am going to start taking pictures of them for my lame ass Flickr page pretty soon. When I found an empty payphone shell one week, there was a new phone in it the next. Local calls are only 25 cents, and I see people on them all the time. I'm not sure if they are COCOTs or AT&T, but they are here and not going anywhere for a long time, in the city of Cicero, IL...
