In my experience, only a minority of people cares about the apps, how the system works or even how the apps looks like... the majority of people choose Android for the imposition of the seller/carrier and the fact of social pressure... example if relatives, friends owns "X" product most likely you will end up buying that "X" product.
I cannot even put iOS in the same league as Android because is so expensive that in many countries is just a minority like WP.
