Kudos to this guy for giving a head start to plenty of indie and starting game devs. I can attest to this as I used Cocos2D to produce my iOS game (since pulled because I have been too occupied this year to hack on iOS: last year of high school = major pressure to do well; very competitive environment). But this is beside the point: Wenderlich's tutorials are awesome, well-written and comprehensive. They won't get you production ready games in a flash, but they sure do help.
From an Indie point of view, iOS game development is considerably more accessible than Android game development by virtue of the following facts:
* Cocos2D is a robust, free and easy-to-use environment; a fully-functional, stable, Android analogue does not exist.
* iOS code is 99% universal (just works on all devices) whereas Android code really isn't. For instance: OpenGL sample code from the Android development guides (http://developer.android.com/training/graphics/opengl/index....) does not work on 2 of 4 android devices I've tried it on because it targets deprecated API's and methods which are unusable using the newest SDK versions (it was version 14 or 15 at the time; largely unimportant). Imagine how disheartening, demotivating and demoralising it is to see that "official Google endorsed code" just doesn't work.
* I have personally tried AndEngine and Cocos2D for Android. Neither is up to scratch with iOS Cocos2D.
tl;dr Ray Wenderlich is indirectly responsible for a ton of Indie games on the App Store, should be thanked, and no, an equal (easy-to-use portable, robust, _decent_ framework) doesn't exist for android (though there may be analogues).
