A mobile computing device includes a first housing that is rotationally coupled
to a second housing, computing circuitry within the first housing and a display
that is at least partially disposed within the first housing. The display is configured
to visually display information from the computing circuitry to a user. A first
user interface device and a second user interface device are at least partially
disposed within the second housing. The second housing is configured to be rotated
relative to the first housing between a closed position in which the first and
second user interface devices are at least partially covered by the first housing,
and a deployed position in which the first and second user interface devices are
at least partially uncovered on opposite lateral sides of the first housing.
