To add to what Pelago said... to clarify how I read qgil: MeeGo Trouch Framework == Actual UI (User Interface) for device Reference Applications == Default Apps maintained/made by MeeGo dev's Nokia Set of Applications == Nokia specific Applications maintained/made by Nokia. The UI + Apps == UX (User Experience) So Harmattan will have a (slightly) different "UX", but the same "UI"..
