Hey, I see lots of threads where people say something like "I hope iTunes 9 is Cocoa based" or "this would be a great app but they need to get off of Carbon", etc, etc. As a user, I've never thought 'wow, this app is Carbon yuck.' Can someone explain to me why anybody cares which framework their app was created in? (Not counting that 64bit now equals Cocoa by default, and they may want 64bit applications) From a USER perspective what does Cocoa vs. Carbon matter?
