Then there is the other reason why we don't need cell phones to be used in the air. It would be simply obnoxious to have half the plane including all the folks in the front cabin yapping on the phone at the same time.

Yesterday, I was walking through St. Patrick's Cathedral in NYC (it was more crowded than usual) and I see this guy sitting at one of the pews talking on his cell phone while others around him were praying in silence. In disbelief, I took four glances over to him and he finally walked out of the church to continue his conversation.
