A portable computer includes a removable I/O device, where the removable I/O device is separate from a built-in cursor control device of the computer so that the computer stays functional without the removable I/O device. Consequently, if the presenter wants to return to the computer and use it directly, he does not have to place the removable I/O device back in the computer, which may disrupt the operating mode. Alternatively, the removable I/O device or both a receiver system and the removable I/O device may be designed to fit in one of PC card slots of the computer when not in use. This alternative enables the presenter to use an existing computer for presentations by simply plugging the receiver system and/or the removable I/O device in one of the computer's existing slots. The computer may further provide for automatic configuration of external video output or internal display modes once the removable I/O device is detached from the computer. This alternative provides additional functionality and convenience for the presenter. |
