Yeah, but the US are just ONE nation of what makes the so-called "first world". In another first world country and leading economic nation, my home country Germany, Android smartphones had a market share of 78% in the last quarter. And it's not that we cannot afford to buy iPhones - it's just that a lot of people rather spend the same money on HTC Ones, LG G2s, Samsung Galaxy Notes and Galaxy S3s and S4s instead. Most young folks over here also no longer think that Apple is cool - the trend is changing.
Apple sells more phones in some countries... and fewer in others. But Apple sells more than enough phones across the world.
When the numbers come out in January... I'm guessing Apple will have sold somewhere north of 50 million iPhones this quarter.
That's plenty... whether Apple is "cool" or not.
