The difference between Cocoa and Carbon apps
MacCentral: The difference between Cocoa and Carbon apps
Wow, MacCentral actually wrote a great (seemingly) original article!
Update: I spoke too soon. I should have known better. It wasn't an original article. It's basically a copy of this article on ZDNet. Sigh. MacCentral.... say no more. (figuratively and literally)
BTW, OutlineXplorer is a Cocoa app.
Quote: "Cocoa developers could literally be ten times more efficient and more productive in building software." If, in the future, Apple should decide to release OS X for x86 or other platforms, applications developed with Cocoa will work on the new platforms.
