Have you ever noticed how computers in movies differ from real ones?
Here goes:

* Word processors never display a cursor.

* You never have to use the spacebar when typing long sentences.

* All monitors display 2 inch high letters.

* High-tech computers, such as those used by NASA, the CIA, or some such
  governmental institution, have easy-to-understand graphical interfaces.

* Those that don't will have incredibly powerful text-based command shells
  that can correctly understand and execute commands typed in plain English.

* Corollary: You can gain access to any information you want by simply
  typing "ACCESS ALL OF THE SECRET FILES" on any keyboard.

* Likewise, you can infect a computer with a destructive virus by simply
  typing "UPLOAD VIRUS."

* Powerful computers beep whenever you press a key or whenever the screen
  changes. Some computers also slow down the output on the screen so that it
  doesn't go faster than you can read. The *really* advanced ones also emulate
  the sound of a dot-matrix printer as the characters come across the screen.

* People typing away on a computer will turn it off without saving the data.

* A hacker can get into the most sensitive computer in the world before
  intermission and guess the secret password in two tries.

* If you display a file on the screen and someone deletes the file, it also
  disappears from the screen.

* Whenever a character looks at a VDU, the image is so bright that it projects
  itself onto his/her face.
