QtQuick is definitely a step forward with respect to touch input and slick animated UIs, but there are things I really dislike about it.
* Javascript. Ew.
* Deployment is a bit of a nightmare. They have windeployqt.exe which helps, but it doesn't automatically copy the MingW DLLs, and all the QML files aren't compiled as resources which is a bit ugly.
* The apps are huge. It's like 50 MB for hello world.
* There isn't very good encapsulation of QML components. All object IDs seem to go in one big namespace.
