Stating that this "seems like something Apple would consider" is a far cry from what this blog post does: take one data point's worth of design value from an existing design for one user, extrapolate that to be one of the lead drivers of said design for all users.
I'm all for giving Apple's designs as much credit as possible, but it's still a far cry from even that to "wow this thing about the design I just noticed that works for me must have been something they considered for the populace at large."
The author made a very astute point that I haven't seen mentioned online before (but one that immediately occurred to me when I heard people bitching about Apple not going to 4+ inch screens). His single data point illustrates a general problem: one handed operation for people with a wide-range of hand sizes.
Remember, Apple sells one basic body shape to its entire market. No single Android phone sells anything comparable to as many units as the iPhone. The body shape has to be usable for 95% of Apple's potential market, which includes everything from teenage girls to grown men. Apple undoubtedly thought about exactly the problem the author raised.
