The integration with Illustrator certainly did look handy. Named layers in Illustrator art work become objects you can refer to in the generated JavaFX code. I remember Adobe announcing Photoshop/Flex integration almost a year ago–is it there yet? This could seriously save lots of the tedious work converting graphic designs into application resources right now.
One thing that became clear to me: JavaFX 1.0 as it was presented today is not ready to build serious enterprisey applications. Yes you can have flying, rotating and fading rectangles. You can display photos from Flickr in those rectangles. You can even embed a media player to display a movie trailer. But almost all components still have to be developed for JavaFX (or rather, reused from Swing). We’re a long way before JavaFX will be a serious competitor to Flex.
