Java EE, Java FX and Java SE are also well supported but this is nothing new :-).
If you are new to NetBeans, don't be disappointed. After a single double-click you will have to start to work immediately. You won't get any extra days to download the plugins and make your IDE work :-)
I will use NetBeans 7.3 (or dev builds) during the airhacks.com and all other events as well.
