To add to this point, it's not comfortable for the majority of users. If you look at a normal distribution of users, they want to cover some sort of number and I'd wager that this screen size is hitting that number.
EDIT: Spelling. I don't know why I mentioned "normal" either.Apple simply wants to cover a majority of users.
Because Apple generally tries to create products that appeal to a large percentage of the population, not "blind faith". It's an observation based on common sense.
I disagree, and I'm presenting as much evidence for it as you are (i.e. none). In which conference was Apple's finding published? Where can I download a PDF of the paper?
