If Operating Systems were Airlines

    DOS AIR: All the passengers go out onto the runway, grab 
             hold of the plane, push it until it gets in the
             air, hop on, and jump off when it hits the 
             ground again. Then they grab the plane again, 
             push it back into the air, hop on, etcetera. 

    WINDOWS AIRLINES: The terminal is very neat and clean, the
                      attendants are all very attractive and
                      the pilots very capable. The fleet is
                      immense. Your jet takes off without a
                      hitch, pushing above the clouds, and at
                      20,000 feet it explodes without warning.

    MAC AIRWAYS: Tickets are expensive. The cashiers, flight
                 attendants, and pilots all look the same, 
                 feel the same and act the same. When asked 
                 questions about the flight they reply that 
                 you don't want to know, don't need to know, 
                 and would you please return to your seat and 
                 watch the movie. 

    LINUX EXPRESS: Each passenger brings a piece of the 
                   airplane and a box of tools to the airport. 
                   They gather on the tarmac, arguing 
                   constantly about what kind of plane they 
                   want to build and how to put it together. 
                   Eventually, they build several different 
                   aircraft, but give them all the same name. 
                   Some passengers actually reach their 
                   destinations. All passengers believe they 
                   got there.
