I don't even have a cell phone!
Most of the time I do not see a need for one. Whenever I am out shopping I overhear people on their cell phones. Most of the conversations are pure crap – talking about what store they are at and how bored they are and how work sucked.
If and when I get a cell phone it will rarely be used and never while driving. Other peoples lives are more inportant than any phone call.
