Part of it sounds wrong, too :).  Aqua is a user interface, whereas 
Carbon and Cocoa are APIs.

Please enlighten me as well.  Speed and antialiasing seem to be the 
primary differences AFAICT, but I'm also a pdflatex user, so there's 
probably something here that I just don't get.

Curt's reasoning suggests to me that an automobile, train, and airplane 
are all forms of transportation; as long as you just need to travel 
from New York to LA, you make your choice of implementation based on 
time and cost.  At some level, Quartz turns everything it displays into 
PDF anyway, so maybe they're all PDF viewers.
