I was holding off moving to Netbeans 6.7 since it didn’t have JavaFX suport yet, but with 6.7.1, JavaFX support has now been added.
The UI for 6.7.1 has been polished substantially from the eye-candy icons and almost excessiveness in 6.5 – it looks a lot more crisp and not as cluttered as 6.5 did. I’ve only just downloaded it and started using it, so no other feedback right now – may post some more later.
