They didn't do it just to be different; it's the result of over 20
years of software development going back to NeXT.  Being reasonably
facile in both (and finding both lacking when compared to real OO
programming languages like Lisp and Smalltalk), I have to say I prefer
Objective C.

This one will sneak up on you - in the Mac developer community there's
a reasonably fascist human interface guidelines contingent, which will
actively hunt you down and humiliate you if you don't use the standard
command key shortcuts.  As a result, they tend to be identical across
different software by different authors.  Not so with Windows or
Linux, though in the past few years Windows has gotten a lot better on
that count.  Then again, they had nowhere to go but up.

Well, yes.  And to be fair, it's not C++.  That helps.

Apple's not perfect, but as they say, it sure beats the alternatives.
