This increases the price tag but may be worth it for some. If you get a bluetooth-capable cell phone, you may be able to buy a bluetooth-capable keyboard for the phone. Once the keyboard is added in as a device, you can use the keyboard and not have to use the cell phone keypad. The keyboard I've found is about 9.5 by 5.0 by 0.5 inches in size and has qwerty configuration.
