You're talking about the adoption of Cocoa and the fact that iTunes still uses Carbon? It's not really a fair accusation. I think Apple would very much like to be able to rewrite iTunes in Cocoa, but they have a problem - it's a cross-platform application. As a result they have chosen to use an API on the Mac that most closely resembles an API available on Windows. They know that iTunes is not exploiting the features available on both platforms to their fullest - perhaps painfully so. It is precisely this type of experience which makes them wish to avoid cross-platform development on their new platform.

I mean Apple really does care about the user experience, more so than any other company that I can think of. And yet even they have not managed to put together a good user experience for their cross-platform app. On the Mac it isn't hooked up to all of the Cocoa hotness, and on the PC, well, the less said, the better.

It is Apple's firsthand experience with the problems you can have during cross-platform development that is informing their decision to strongly discourage such development on the iPhone platform.
