Eclipse and Netbeans are both horrible slow, and I'ts a miracle that even the serious developers has been sticking with it for years, not even try to stick with a better product.
Java as platform is a shame when it comes to non-handheld platforms (win,mac,linux) and if anyone are going to develop on the platform I say do what else but do not use Java at all. For mobility it's probably has a kind of good luck here, as the systems are more down-scaled.
As far I know, there aren't any existing IDE for Java which aren't iself written in a Java environment. This is horrible because Java is messing up the desktop environment.
I'm willing to spend hours on google to find an Java IDE/Editor which are capable for android projects but will use a native environment for itself.
