On the other hand we should consider that Google is collecting constantly much more money by giving license of Android usage to mobile phones manufacturers and their earnings are per device. Thus we all enjoy only 20€ in Google play store developer account.
The same is valid for Apple. It does not provide iOS to other mobile phone manufacturers and thus it rolls the cost to devices and developers.
Both companies are living organisms who need to be feeded to produce and give us their "products" although now that I think about it the previous sentence looks kind of disgusting.
As a developer though I believe that Android is much much much better than iOS since it provides a lot more opportunities and it does not totally break your b@lls out of caring for security...
