I somewhat regret this, as I miss the Touch ID. Rumors are the 13 models will have a Touch ID under the screen, which will be great, but, I don't know they'll have a 'mini' version either. Apparently the 12 mini is being discontinued? I can't tell if that rumor is true, or production is just being reduced in favor of the larger models. Either way, the "small form factor" just seems to be an afterthought.
Was reading a few viewpoints on this (perhaps it was even on HN?) some time ago, and ... one of the attractions of 'big screens' is that, for most people, that phone may be their only or primary internet access device. For me, I'm on laptops and large screens all day - I want small and conven ient and mobility in a phone, not large screens. If I want a large screen... I go to a large screen. I don't try to wrestle with getting a 7" device in to pockets to carry around with me. But people wanting 5" phones are apparently in a minority.
