In a word, Android. Google pretty much requires one to use Eclipse in order to develop Android software. Obviously one can struggle to get around this assumption, but the adjustments required take more effort than using Eclipse, granted its many limitations.

Google's IntelliJ-based Android Studio is at version 0.4.2. It's still a little rough but very promising. I suspect when it reaches 1.0 or thereabouts, Eclipse numbers will go down.

But Eclipse is still pretty useful for creating Java web services.

Google has switched to Idea with Android Studio: http://developer.android.com/sdk/installing/studio.html
