Ask HN: what do you guys think of JavaFX?

In the RIA world, with the release of proprietary frameworks+runtime such as Flex, Silverlight and opensource HTML+JS based frameworks such as cappacino and sproutcore, how does JavaFX stack up? Anyone has played with it yet? is it simply Java applets of the late 90s again or is it something worth learning and looking into for building rich-media applications?
