AFAIK, the only way to develop iOS is to buy a Mac, which would put me out however much money. Then I have to pay a yearly fee to get on the App Store. Then I have to learn Objective C, a language which only Apple uses for all practical purposes. Then I submit the app and see if they accept it or not.

With Android I can code, compile and deploy on any platform. Google Play is a $25 lifetime free, the $25 mostly to prevent fraud. I can program in Java, a language taught to virtually every CS student and which can be used in a variety of circumstances. No approval for new or updated apps, it just goes onto Play.
