Cellular Devices in Class

Cell phones are an important device in the world today. We are not allowed cell phones in class; but why? We are the only school in our division that isn't allowed cell phones in class. We are being under prevailed by not being allowed to use our cell phones in class. This needs to change.
In our school we are only allowed to use computers for technology. A computer is very useful but not the most efficient device. A cell phone is more useful than a computer. A cell phone has the same applications as a computer does but is a pain. A cell phone is smaller, easier to use and you can rely on the batteries. This should be a no brainier to use the better technology.
