Summary
  • Sales of laptop portable computers are approaching those of desktop models. The portable computer is available in three categories: (1) the lightweight portables-weighing under five pounds; (2) the medium weight machines, between five and ten pounds; and (3) the heavyweight IBM PC compatible machines-weighing over ten pounds. Major components involved in design of portable computers and their associated design constraints are: (1) the display, still the single greatest challenge; (2) the keyboard, which must be convenient and functional; (3) the microprocessor and memory, which must be convenient and functional; (4) the microprocessor and memory, which must minimize power consumption while maximizing operating speed; (5) disk drives, which are currently 3.5-inch microfloppy drives, with a 1.4 Mbyte floppy drive release expected in the summer of 1987; (6) pointing devices, which are most commonly cursor keys, but with mice, trackballs, and touchpads under development; and (7) weight and size, which are targeted to make a user inclined to take the laptop machine along if even a remote chance exists that it will be needed. The only other major consideration is data exchange between the laptop and desktop computers. This can be accomplished by floppy diskette interchange, use of a null modem, or highspeed serial cable connections.
