Define more popular then for me.
Ok. In the car world, Toyota is i think the highest share of the market. They sell all types of cars, 3 door to SUV. As do others. Ignoring the Ferraris, Mercedes of this world, Toyota sells more than its competing car manufacturers. So, they are more popular, given that the Hyundias, etc are similar cars, prices, the consumer has made the choice that Toyota is more popular as seen in sales.
Smartphones. Same, except with iOS and Android there is major difference. iOS phones are only in the high end. They don't sell in the budget end, or mid range, perhaps if you include last years phones they still operate in the upper mid range.
Android sells from high end to the budget end, and the very budget end.
So, to see the popularity you need to get a level playing field. Exclude all smartphone sales to very budget, budget, lower and mid mid range, then check the numbers.
I recall seeing recently that in the US, iPhones were about 50%, I cannot recall if that was installed phones or the last quarter. Deduct from all the sales, the very budget to mid midrange, then see what that 50% is.
And, up till now, the fact that Apple chose not to sell normal sized phones, meant that it lost sales to buyers who wanted iOS but 4.5" and bigger. Apples choice. The popularity is not matched by sales, its matched by sales of Android/WP by default.
The price to Apple, is lost sales as they do not compete in the very budget to mid midrange, their choice. The cost to other manufacturers is that they do sell in those markets and continue to make no money or lose money, their choice.
Samsungs phones retail for similar to the iPhone equivalent, then they discount by 20% a month after release. I read today that they are now 40% less then the release price for current phones. That doesnt seem to help.
Popularity is selling the most items, which can only be measured when there is a level playing field. Or by removing the non competing items to see what the sales are for each manufacturer selling equivalently priced items.
