Depends how you quantify "desirable" but since there are many more Android phones in the world than iPhones, some would say that means Android phones are more desirable. But either way, that really has little to do with profits. If I sell just one item in my entire life for a million bucks, something that cost me ten bucks to make, that is pretty impressive profits, even though it was not desirable since only one person bought it.

I think you can only associate desirability with units if you hold other things equal: price, availability, etc.
