The future trends in personal computers from the Las Vegas Consumer Electronics Show, January 1981:

“Toshiba introduced what could be the most significant product of the year for the personal-computing market:a pocket-size flat-screen television set.  While no specific mention mention was made of its possible use with a personal computer, it takes only a moment’s thought to see the potential of this engineering marvel. […] The Toshiba television has a 4.1 by 3.1 cm (13/4 by 1 1/5 inch) LCD screen.“

“Sony has introduced a new electronic “typewriter” that fits in a briefcase and lets you enter, store and edit up to 200 pages of text, using a built-in microcassette recorder.  Text is displayed on a one-line liquid-crystal display. Combine such a device with a flat-screen multiline video display and you have a very attractive concept, indeed.

Another Sony breakthrough is a new miniature floppy-disk system.  Each disk measures 8.9 cm (3 ½  inches) in diameter and holds over 800,000 bytes!“
