It's amazing how some think their personal experience represents meaningful statistics that holds true when applied to tens or hundreds of millions of people.
He asked about "real world" experience and so simply I responded with mine. What's so difficult about that for you to understand?
I bet that unless you work in a very small office, not even your 60-40 split is correct. Perhaps it's just your confirmation bias - you probably simply notice iPhones a lot more then other phones. Perhaps people with iPhones keep them more visible/show them off a lot more than other people (since the iPhone is fashion tech, that would make sense).
I wouldn't call an office with over 500 employees on 8 floors "small" but whatever you say. And no, I go by what I actually see every day, not any confirmation bias. If anything, 60/40 may actually be underestimating it here by a little bit. However, you're more than welcome to come here and look at all 500+ employees phones if you'd like to actually prove yourself either right or wrong, since you seem to think that you know so much about it.
