I’m very confused by JavaFX - just what is it for? I thought it was the Sun’s answer to RIA/Air/Flash/Flex/Silverlight but every demo I see it about producing Swing frame’s for bouncing balls or fancy graphic text. I know this isn’t the final release, but I can’t get to the bottom of the hype!

I don’t understand the overlap with Groovy Swing/GraphicsBuilder which seems to offer a large majority of the demonstrated functionality of the JavaFX and offers more power and better integration with Java itself. (Admittedly there are additional media, etc elements to JavaFX).

All this isn’t helped by the fact I can’t get my hands on it. Verying disappointing that there’s no Linux distribution (even feature limited version). This is particularly frustrating as it has been demonstrated that it is possible to hack the current Mac JavaFX SDK to run on Linux (just not supported officially).
