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.
