1. A portable information device configured to receive executable instructions from a computer via a disk drive having a magnetic read/write head, the portable information device comprising:

  • a protective encasing having a form factor of a 3.5" memory diskette, the encasing being insertable into and removable from the computer disk drive;

    a magnetic medium-emulating transducer positioned in the encasing to lie adjacent to the read/write head of the computer disk drive when the encasing is inserted into the computer disk drive, the transducer generating magnetic signals that simulate a rotatable magnetic medium to communicate with the read/write head of the computer disk drive;

    an input mechanism accessible from an exterior of the protective encasing to permit a user to enter information when the encasing is removed from the computer disk drive, the input mechanism being within the form factor of the protective encasing;

    a memory provided within the protective encasing;

    a processor operatively coupled to the memory and to the transducer, the processor receiving executable instructions and/or data from the computer via the computer disk drive and the transducer when the encasing is inserted into the computer disk drive, the processor loading the executable instructions and/or data into the memory;

    the processor also being coupled to receive the information entered by the user on the input mechanism when the encasing is removed from the computer disk drive, the processor operating on the information according to the executable instructions stored in the memory; and

    an audio sound generator operatively coupled to the processor the audio sound generator generating audio sounds which are emitted from the portable information device.
