Handheld electronic device with extended dual-hinged interconnector

1. A clam-shell style handheld electronic device transitionable between open and closed configurations, said device comprising:

a display housing pivotally coupled by a dual-hinged interconnector to a keyboard housing, said display housing having a display screen located at an interior surface thereof facing a keyboard on an interior surface of said keyboard housing in the closed configuration of the device and wherein at least one of the display housing and the keyboard housing includes a camera to the exclusion of the dual-hinged interconnector, the dual-hinged interconnector being disposed between a pair of hinge ends for each of the display housing and the keyboard housing;

said dual-hinged interconnector having a thickness substantially equal to a combined thickness of said display and keyboard housings in the closed configuration of the device; and

said dual-hinged interconnector having a length greater than at least twenty percent of a length of the longer of said display and keyboard housings and wherein lengthwise longitudinal axes of each of said display and keyboard housings and said dual-hinged interconnector are oriented substantially parallel, one to the others, in the closed configuration of the device.

2. The clam-shell style handheld electronic device as recited in claim 1 , wherein an interior angle formed by the lengthwise longitudinal axes of said display and keyboard housings are oriented at an obtuse angle to one another in the open configuration and the lengthwise longitudinal axis of said dual-hinged interconnector is oriented at an obtuse angle to the lengthwise longitudinal axis of at least one of said display and keyboard housings in the open configuration of the device.

3. The clam-shell style handheld electronic device as recited in claim 2 , wherein the lengthwise longitudinal axis of said dual-hinged interconnector is oriented at an obtuse angle to both of the lengthwise longitudinal axes of said display and keyboard housings in the open configuration of the device.

4. The clam-shell style handheld electronic device as recited in claim 3 , wherein said dual-hinged interconnector has a width substantially equal to a width of each of said display and keyboard housings, said widths measured in a direction substantially perpendicular to said lengthwise axes in the closed configuration of the device.

5. The clam-shell style handheld electronic device as recited in claim 4 , wherein said thicknesses are measured in a direction substantially perpendicular to said lengthwise axes in the closed configuration of the device.

6. The clam-shell style handheld electronic device as recited in claim 4 , wherein said thicknesses are measured in a substantially vertical direction in a resting orientation of the device in the closed configuration.

7. The clam-shell style handheld electronic device as recited in claim 5 , wherein said lengthwise longitudinal axes extend in a substantially horizontal direction in a resting orientation of the device in the closed configuration.

8. The clam-shell style handheld electronic device as recited in claim 3 , wherein said widths are measured in a substantially horizontal direction in a resting orientation of the device in the closed configuration.

9. The clam-shell style handheld electronic device as recited in claim 1 , wherein said dual-hinged interconnector has a navigation device located at an interior surface thereof in the closed configuration of the device.

10. The clam-shell style handheld electronic device as recited in claim 9 , wherein said navigation device is a trackball assembly comprising a trackball, said trackball assembly being predominantly housed within said dual-hinged interconnector and a portion of said trackball being exposed at the interior surface of said dual-hinged interconnector in the open configuration of the device.
