Claim:
A device comprising: an upper unit having a display screen thereon; a first slidable unit having a first keypad thereon, the first slidable unit being slidably connected to the upper unit on a side opposite the display screen, the first slidable unit being movable between a closed position in which the upper unit generally overlies the first keypad and an open position in which the first keypad is positioned generally adjacent the display screen; and a second slidable unit having a second keypad thereon, the second slidable unit being slidably connected to the upper unit and the first slidable unit; the second slidable unit being movable between a closed position in which the upper unit generally overlies the second keypad and an open position in which the second keypad is positioned generally adjacent the display screen; wherein the second slidable unit generally overlies the first keypad on the first slidable unit when the second slidable unit is in the open position, and the first keypad on the first slidable unit is accessible to the user when the second slidable unit is in the closed position and the first slidable unit is in the open position, and wherein the second slidable unit is received in the upper unit in the closed position; wherein the second slidable unit is configured to engage with the first slidable unit when the first slidable unit is moved from the closed position to the open position so that the second slidable unit moves together with the first slidable unit from the closed position to the open position; wherein the second keypad of the second slidable unit is accessible to the user and the second slidable unit overlies the first keypad of the first slidable unit when the first and second slidable units are in the open position; wherein when the second slidable unit is in the open position, the second slidable unit is configured to disengage with the first slidable unit when the first slidable unit is moved from the open position to the closed position so that the second slidable unit remains in the open position and the second keypad is accessible to the user.
