What is it with iPhones??

Look right; look left; everywhere you look, you will see someone with an iPhone. WHY?

Are Americans buying iPhones because everyone around them has iPhones so that you can use Apple exclusive services like facetime and imessage? I have seen some really broke looking people with iPhones (and I know i shouldn't judge based on one's appearance but) then there are also people with broken screen iphones who can't get them fixed because it's expensive for them.

Is it because iPhones are american? So is android and you can go with Google or Samsung (it's not chinese)

Why iPhone?
