How to modify the device?

1. Remove the right side thumbwheel button.
2. Add a Back Center Wheel Button at the top of the back. (Please see the drawing). The Back Center Wheel Button is about the half length of the width of the device, so it is much easier for index fingers to scroll it.

Why the Back Center Wheel Button is better than the side thumbwheel button?

1. Both left-hand people and right-hand people can use it easily. Therefore, customers will enjoy BlackBerry using both hands, and they can free the other hand to do other stuff.
2. The index finger is usually the most dexterous finger of a hand. (Quoted from WIKIPEDIA)
3. The Back Center Wheel Button is much wider and bigger than the normal side thumbwheel button, so it is much easier to be scrolled.
4. It makes the device more symmetric, and more beautiful. (Beauty as a result of balance or harmonious arrangement.)
5. When you hold both sides of the BlackBerry using your thumb and the rest three fingers, you will hold it much steadier.
