I've been with an iPhone since the 3G and have marvelled at the consistent "smaller, lighter, faster".
The recent trend to bigger phones, or "bigger than bigger" as Apple brands it, is confounding. The iPhone 5 screen stretch was a bit annoying, as the 4S was great, but remember
this ad? It seems that Apple can be pressured from their well-conceived designs by
marketing-related fears despite their poking at MSFTs "scatter-brained"* approach.
It's a shame.. and this is the first major iPhone update that I have had zero interest in purchasing and intend to self-repair my iPhone 5 if necessary as it starts to break down to stay within iOS and away from the awkwardly massive screens. I held an iPhone 6 (not the Plus) and it is uncomfortably large - had to shift it more precariously into my fingers to give my thumb the flexibility to reach all that extra useless screen space. The feature to draw the screen closer to the bottom, even in the 4.7" model, is the clearest argument that the phone is too damned big and should never have hit store shelves. I hope the shift to larger phones is neither motivated by a desire to merge the iPhone and iPad SDKs nor leads to such a merger making it difficult to shrink the phones again in the future.
Any screen size increase should have eaten away at the bezels, not pushed the overall dimensions outward. And I really wish they'd rethink this bigger is better nonsense.. that's a tablet's design space. It is indeed bigger than bigger, but blunderously so. Phones should be smaller, lighter, faster.
Apple's marketing-related improvements should have been on their perpetually backwards hardware specs and, to draw more away from jailbreaking, further customizability of their devices (ie: a 5th column). There's nothing wrong with shipping with 1GB RAM if it cannot be filled for most uses over the next few years except that
consumer ignorance and direct comparisons to competitor phones can't help but cost Apple sales. Now, if time shows that the 1GB is a engineered obsolescence factor (like the 3G's memory restriction did with future iOS releases) then the consumer frustration will be quite justified.
I hope the iPhone 7 shrinks back to more reasonable dimensions and that Apple's notion of customizability extends further than
"we also introduced a dark mode!" - nice as it is.
