> You don’t know anyone who uses an iPhone to browse the web?

What you write as a joke is in my opinion not one: when I consider the department hallway in the office where I work at (not tech sector), you will, I think, only find 2 iPhone owners among about 25 people. One of these iPhone owners is the boss, and the other one is a programmer who vocal about not liking Android.

So, depending on your surroundings, it is quite possible that seeing iPhones or iPhone owners is actually a somewhat rare event.
