A portable computer system is provided having a base unit and a detachable
display unit. The display unit can be attached to and supported by the
base unit in a landscape orientation or a portrait orientation via one or
more connectors provided on two different sides of the display unit. The
base unit may include support pins providing physical support to the
display unit. Alternatively, the base unit may include a support arm
which attaches to and slides within a slot extending along two sides of
the display unit, such that the display unit can be moved between
landscape and portrait orientations.
