"If Operating Systems Were Cars" joke

If various operating systems were cars, what would they be?
Linux is the Fiat of operating systems, it's fun when it's not broken.
Eventually, though you'll get fed up and get something better.
Windows NT is a 1964 Mercury Monteray, it's big beyond big and a
real waste of our resources. It makes a lot of noise, though.
MS-DOS is a Tyco slot racer. It's a silly toy that takes you around and
around in circles.
MacOS is one of those talking cars. Some people think they're neat.
The rest of us want to break them.
Emacs is a M1A1 Abrams tank. Ok, so Emacs isn't really an OS and an
Abrams isn't a car, but they're both close and they're both BIG.
AIX is a mail truck. When you're using it you keep wondering why
everything is this backwards!
OS/2 is one of those 3 cylinder Geo jobbies. People who use 'em brag about
how efficient they are. The rest of us think they should get real.
VMS is a Volkswagon Beetle. When you see 'em you turn, punch your friend
in the arm and laugh. The strange thing is, you still see them around!
AmigaDOS is a DeLorean. Sure it's pretty slick and all, but they're just
not made anymore.
