Handheld mobile communication devices according to the disclosure have a closed position, in which the display member of the device covers at least a portio n of the keys of on the keypad member of the device, and an open position, in which the keys are accessible and the device is operated. When the display member is in the ope n position, it forms an ergonomically desirable angle (e.g., on the order of about 155 ) relative to the keypad member. However, unlike clamshell-type cellular phones, the display member does not simply flip open about a conventional pivot joint. Rather, it moves from the closed position, where it is parallel and adjacent to the keypad member, to the open, angled position through a sliding/sweeping motion; through an eccentric, "up - and-over" rotational motion; or through a combination sliding/"up-and-over" motion.</S DOAB>
