If half doesn’t make you leader what does? Maybe you should elaborate your definition of leader? For me it’s “has the highest market share”. And in that definition half is necessarily true.
It’s funny that for PC’s you went for manufacturers (apple is 4th) but for mobile you went for OS (Apple is 2nd). On mobile devices, Apple is 1st, having double market share compared to 2nd place (samsung).
The need to paint Apple as purely a marketing company always fascinated me. Marketing is a big part of who they are though.
