If you create a sample project with a list view, you can scroll that widget by clicking the mouse on the background and dragging it (a reminiscence from touch based interfaces). The example projects don't look native but look like a mobile app inside your desktop. Windows themed button sizes don't follow Windows 7 desktop guidelines out of the box.

Sure that if you put the extra effort you can make QML look native, but it makes you wonder if desktop is in fact a goal for the framework.
