It wasn't an advocacy piece, it was a developer's experience in changing environments, and giving some pointers on what to do differently in Android than what one is used to in iOS. The point is not to convince you to develop for Android. The point is to help someone make the switch quickly (such as using Eclipse rather than some other method that hardly anyone uses which will cause you to spend hours getting things set up and a lot of pain following a how-to that is written with the assumption that you're using Eclipse because, you know, almost everyone who developers for Android does).
