All this reminds me a quote I found in an old PC Week: "Objective-C is the result of adding object facilities to C with the goal of making programmers more productive. The result differs greatly from C++, which adds objects to C without making computers less efficient: quite a different goal." [PC Week, November 3, 1997]
I think bbum hit it on the head. We can get some seriously awesome optimizations out of C++, but the purpose of this languages is ultimately quite different from the purpose of Objective-C (as I see it). C++, from what I understand, is meant to be a computer efficient OO language, whereas Objective-C was designed to be a "programmer efficient" OO language.
