I wrote this almost exactly three years ago, to much debate:
Sure, Apple will most likely still make far more money per sold iPhone device than competitors will per Android phone, but the trend is clear: as much as I love my iPhone, it will be relegated to a ~10% market share figure within a few quarters.
It took a little longer than “a few quarters”, but here we are. Android has revolutionised the smartphone market. I’m not particularly happy about that (both Android and Samsung are far too dominant, which is bad for the market and thus for consumers), but there it is.
