Abstract
An improved mobile electronic device 100 with a unique thin and cost-effective form and design can have a large display 170 in the outward surface of a flip 102, a large full qwerty keypad 138 in the outward surface of a base 108, and a touchpad 186 in the inward surface of the flip. This arrangement provides useful zooming functionality and magnification techniques, as well as the ability to navigate the display using the touchpad while assuring that the full view of the display is not blocked. This arrangement also accommodates changing the mode of the touchpad from a navigation mode to a zoom mode and vice versa.
