A communication device (10) having a front housing and first and second independent keypad housings (14 and 16) having respective keypads functionally connected to the front housing (12). The front housing has a speaker (18), a microphone (20), and a display panel (22). Each keypad has a key configuration that is different than the other. The front housing (12), first keypad housing (14), and second keypad (16) housing are constructed to overlap and stack in a nested configuration in which each of the keypads (14 and 16) is concealed by the front housing (12). The front housing (12) is movable relative to each of the keypad housings from the nested configuration to an extended position in which one of the keypads is exposed and physically accessible by a user. |
