You mean portable to the MacOSX Foundation library. (Almost) nothing
prevents one from using GNU ObjC on MacOSX ?!
The situation is pretty much the same like with Java.

Ok. You mean that they have the same syntax like classes. This may or
may not be an advantage. Eg a side-effect is, that they live in the same
namespace, which is sometimes annoying (eg @interface
NSObject<NSObject>).

No. You can use the _objc_class_lookup callback to implement ClassLoader
like mechanisms. Indeed our SKYRiX server uses this extensivly.

Ever tried

- doIt {
for(int i=0...) {}
for(int i=0..) {}
}

and wondered about 'i' symbols declared twice ? ;-)
