With a very biased verdict.
I was going to post something just like this, but you beat me to it.
Eclipse is "the devil you know" for 99% of Android developers (and probably a majority of Java developers). It may not be as great as IntelliJ or IDEA or NetBeans for somethings, but it's functional and has worked well for a long time. It's got plugins for everything, good git integration, decent UI build tools, good support for JNI and ABI cross compilation, and it was used for 99% of the apps in the Google Play store.
This Android Studio IDE may very well be awesome (I haven't tried it as Eclipse works for me), but this article does not make any case for it whatsoever.
