You drag / drop stuff into the actual folders, not the paths. For whatever reason I find myself wanting to drag something up to one of its parent folders fairly often, and I'd rather not have to dig around in the navigation pane tree (which I tend to keep hidden) or open a new window and navigate back etc. Though speaking of copying paths, Win8 also puts a Copy Path button on the ribbon home tab (you can pin it to the QAT for use even with the ribbon minimized) which is marginally nicer than having to Shift-rightclick.
