Cellphones are the downfall of this once great nation! I will not own a cellphone. Cellphones have made people less productive, not more productive. Cellphones have made people dumbem, not smarter. Cellphones have cost more lives in accident than saved them! People have lost their ability to plan ahead thanks to cellphones. People have lost their common sense and common courtesy thanks to cellphones. And people don't know how to use their inside voice thanks to cellphones! I can't wait until somebody develops a signal blocker and restaurants and bars start banning them completely. I don't like cellphones.
