Who hasn't? It was Nextel Push-to-Talks first and then Blackberries (and of course the lovely BES to manage all the stupid things)

OMG those were the dumbest things ever. People just didn't understand what an idiotic idea that was. The normal phone was push to talk to, and both cases required the other party to answer. There was no upside. But once you made a call, it was this slow, annoying one person at a time audio that made it horrible to talk. There was no upside and huge downsides. They are a shining example of how easily you can dupe huge swaths of people with marketing even when it is completely clear that you are being fooled.
