This was actually a very interesting experiment. One thing I didn't do that I knew would require quite a bit more code on my end is try and implement some binding from the textfield which is done in the JavaFX example.
I definitely agree that it's an interesting experiment, and moreso to see it put into practice.
I suppose the question I would have - and this is one that is more of a "wait and see what ends up happening" - is the matter of acceptance in the marketplace. How many practicing developers are going to go so far as to try JavaFX and swap over, and will it gain traction? The simplicity is one thing, but I've met far too many dyed-in-the-wool process guys...
