All the flight attendants, captains, baggage handlers, ticket
agents look the same, act the same, 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, until the
flaps and rudder freeze in which case you will have just enough
time to say your prayers before you crash.
Windows
Colorful airport terminal, friendly flight attendants, easy access
to the plane, uneventful takeoff. Then: BOOM! You blow up without
any warning whatsoever.
NT
Everyone sits on the runway and forms the outline of an airplane,
and then makes the sound of an airplane taking off.
UNIX
Everyone brings their own piece of the airplane. Then they go to
the runway and piece the plane together, all the while arguing what
kind of airplane they're building.
