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 (14, 16) and permit rotation of the first and second displays (20, 22) 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 (20, 22) are in the closed face-to-face orientation; and a magnetic closure system configured to retain the first and second displays (20, 22) 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 (20, 22) are in the closed face-to-face orientation is configured to permit 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, wherein: the magnetic closure system includes a first magnet arranged in the first housing part and a second magnet arranged in the second housing part, the first and second housing parts (14, 16) are held in the closed face-to-face orientation via a magnetic force between the first and second magnets (26, 28), the magnetic closure system is an electro-magnetic closure system that includes an electric motor which is formed to have a threaded portion configured to engage with a nut, the nut being attached to a magnet housing which holds one of the first and second magnets (26, 28) via a housing arm, engagement of the release actuator on one of the first and second housing parts (14, 16) is configured to actuate the electric motor to move the first magnet, movement of the first magnet reduces the magnetic force between the first and second magnets (26, 28), and the reduction in the magnetic force permits the first housing part to rotationally separate from the second housing part to the predetermined angular orientation. a first housing part including a first display;
