1. A mobile computing device comprising:
a first housing part including a first display;
a second housing part including a second display;
a hinge assembly configured to couple the first and second housing parts and permit rotation of the first and second displays from a closed face-to-face orientation to a back-to-back orientation;
a spring-loaded opening mechanism arranged in the hinge assembly and configured to bias with a biasing torque the first housing part and second housing part to rotate away from each other when the first and second displays are in the closed face-to-face orientation; and
a magnetic closure system configured to retain the first and second displays in the closed face-to-face orientation against the biasing torque of the spring-loaded opening mechanism, and including a release actuator, wherein actuation of the release actuator when the first and second displays are in the closed face-to-face orientation permits the first housing part to rotationally separate from the second housing part to a predetermined angular orientation due to the biasing torque of the spring-loaded opening mechanism.
