The competition of ideas on this topic was held by the American firm Apple, which created the first personal computers in 1976.
The competition was won by a group of students at the University of Illinois.
The winners imagine the computer of the near future as a box the size of a thick common notebook. On one side of the box - a color screen on liquid crystals.
There are no keys or buttons other than the power button. Images of keys with the usual set of numbers, letters and symbols appear on the screen when the computer is turned on.
To enter text or numbers into the car, you need to touch the images of these keys on the screen.
Another way is to write directly on the screen with any pointed object.
Written is stored in memory either in handwritten form, or at the request of the owner is translated into typewritten text, which is immediately reproduced on the screen and can be printed on a printer connected to a computer.
In the same way, you can memorize various graphs and curves.

Radio communication with the system of navigation satellites and the transport data bank will allow the owner of such a computer to find out his location on the planet with an accuracy of several meters at any time and quickly calculate the shortest and most convenient route to any other point.
And if such a computer is kidnapped, you can immediately find out where he is, by broadcasting his personal callsign.
