I have a Smart phone only so I can take pictures in an emergency or while shopping & want to remember something. I don't even know my cell phone number. My phone is for emergencies only or for long distance calls, so I don't give me number to doctors, etc. as a week might go by before I saw the missed call. I also refuse to text. If I'm not available to answer my house phone, than there is an option to leave a message on my answering machine. I think this being available to answer and return a call "immediately" is ridiculous. I stopped going to lunch with a friend as I got disgusted with just watching him on his phone or computer.
