? The speed of development (which is excellent) is exactly what is causing the deprecation (unless there is a clear platform level strategy) - Qt development is a moving target and by the time a proper (as in, non-beta, MeeGo supporting) Qt SDK is released, Qt4.7 will be almost be upon us. And yet, if we want to write software compatible with the existing Qt compatible devices (N8, N900, probably Harmattan device) we will have to target a generic Qt4.6 version unless it is clear that there is a clear intention that the platforms of these devices intend to keep up with the upcoming Qt versions. The painful part is that QML *does* make things a lot easier so it is a real drag to do manual QPropertyAnimations when you know QML is coming/available. The intra-Qt platform specific widget frameworks and modules only aggravate this problem.
