Agreed. QT is by a very extreme margin the most competent I've seen. On an absolute scale, I'd still classify it as mostly incompetent. I still agree with the Mono team - your model and view model should be xplat, while your view should use platform-specific APIs.

Android users don't expect Android interfaces to work like iPhone interfaces and visa-versa. You can do all the skinning in the world but the underlying workflow of the interface won't match the platform.
