A portable communication apparatus, such as a mobile telephone, has a main apparatus housing, a first user interface with a first keypad, such as an ordinary telephone keypad, and a first display. The apparatus also has a second user interface with a second keypad, preferably a typewriter-type keyboard, and a second display, which preferably is larger than the first display. The second keypad and the second display are detachably connectable to the main apparatus housing of the portable communication apparatus. |
