Could you give an example which inconsistencies are the most offending to you? I agree that some platform specific behavior is important. But only behavior that relates to OS, like window management, system dialogs, accessibility etc. IMHO we are focusing too much on what does and doesn't look like platform UI. Big part of native widgets is also about branded UI. Arguing weather Apple or Adobe is more important brand for the UI is kind of pointless. Consistent UI across multiple platforms affects more than just people who are using multiple OSes. For example, user watching a tutorial, expects to be able to replicate instructors actions. Imagine the joy of discovering in-app menus on his machine are different, because instructor was using the app on a different OS. Also, greater cost of designing and developing widgets for different platforms means there is less budget left to design custom task-specific UIs with better UX. For UI "inside" the app, we should be focusing on what is a best possible UX of human-computer interaction for a task at hand. Just blindly using native widgets for everything can actually lead to bad user experience. For example, I hate it when an app uses Win32 Color Dialog for color selection. It's a widget with a bad UX for 99% of use cases. To me, as a user, UI with good human-computer interaction experience is much more important that use of branded platform-native widgets.
