That's one thing that always drives me nuts when I'm watching computers being used on TV or in the movies... EVERY user interface element BEEPS. Text will scroll on the screen (no idea why it won't just show all at once) and as the computer renders each and every single character, it lets out a beep. That sort of machine would drive me nuts after about 3 minutes of use.
John Badham (director of WarGames) explains it quite well on the director's commentary for WarGames - Movie studio executives insist that when something happens on-screen, it must have an associated sound so the audience knows something is happening. Everyone knows a computer doesn't beep every time you press a key. But just like most people require tactile feedback when typing for optimum performance (one of the multitude of reasons Star Trek's LCARS input interface will never truly be embraced in reality), studios insist the audience needs aural feedback when something is happening.
There are two ways to write error-free programs; only the third one works.
