Here's some descriptions of airplanes run by various operating
  systems:

  DOS:  Everybody pushes it till it glides, then jumps on and lets it
  coast till it skids, then jumps off, pushes, jumps back on, etc.

  DOS with QEMM:  Same as DOS, but with more leg room for pushing.

  Macintosh:  All the flight attendants, captains and baggage handlers
  look the same, act the same and talk the same.  Every time you ask a
  question, you are told you don't need to know, don't want to know and
  everything will be done for you without your knowing, so just shut up.

  OS/2:  To get on board, you have to have your ticket stamped 10
  different times by standing in 10 different lines.  Then you fill out
  a form asking how you want your seating arranged--with the look and
  feel of an ocean liner, a passenger train or a bus.  If you get on
  board and off the ground, you will have a wonderful trip, except when
  the rudder and flaps freeze, in which case you have time to say your
  prayers before you crash.

  Windows:  Colorful airport terminal, friendly flight attendants, easy
  access to a plane, uneventful takeoff.  Then:  BOOM! You blow up
  without any warning whatsoever.

  NT: The terminal and flight attendants all look like those the
  Windows plane uses, but the process of checking in and going through
  security is a nightmare. Once aboard, those passengers with first
  class tickets can go anywhere they want and arrive in half the time,
  while the vast majority of passengers with coach tickets can't even
  get aboard.

  Unix:  Everyone brings one piece of the plane.  Then they go on the
  runway and piece it together, all the while arguing about what kind
  of plane they're building.

  CAIRO: The airplane is distributed among 47 different hangars in 13
  airports scattered over 8 states, 4 Canadian provinces, and a remote
  mountain hideaway in Nicaragua. But you don't need to know where the
  airplane is or who it belongs to in order to fly it. Actually, you
  don't fly the airplane itself; you fly a simulation that behaves just
  like the real thing except that you don't go anywhere. But that's
  okay, because when the world is at your fingertips you never need to
  leave home.
