Some of you folks sound like Luddites. If you prefer to have your friends call you on your home phone, not your cell phone, tell them so. If you'd be embarrassed by having your cell phone ring during a concert, turn it off or mute it. If you think it's rude to make fellow travelers on a bus hear your private conversation on your cell phone, don't do it. Cell phones have some good uses. One that has not been mentioned here yet is receiving phone calls when you're on the Internet if you don't have broadband.
