a housing that comprises a top edge, a bottom edge, a front side that comprises a display operatively coupled to display circuitry and a back side that comprises, ordered from the bottom edge to the top edge, a ferromagnetic surface, a hinge assembly, and a recess; and

a ferromagnetic panel transitionable via the hinge assembly from a storage position in the recess of the back side of the housing to a bridge position that covers the ferromagnetic surface of the back side of the housing, wherein the ferromagnetic panel comprises a first sub-panel and a second sub-panel that comprise ferromagnetic material, wherein the first sub-panel is coupled directly to the hinge assembly of the back side of the housing, and wherein, in the bridge position, the first sub-panel covers the ferromagnetic surface of the back side of the housing and is secured to the ferromagnetic surface of the back side of the housing via magnetic force, and the second sub-panel extends beyond the bottom edge of the housing for magnetic coupling of the device to another device.
