It seems like drag-and-drop is out of fashion. I think big reason is that it really cannot be done well on touch-screen devices and touchpads. I don't really complain, because I have always found d&d rather impractical (and it's also terrible for accessibility); unfortunately, there are some applications that still rely on it a lot.
(As an aside, what bothers me more that the right-click menu goes out of fashion. That I feel is a bigger usability problem.)
