I'll preface this by saying I really like my 6. Returning to the rounded edges of the original and the gorgeous screen make it a worthy upgrade over my 5.
There are two areas of the phone that just don't seem to have the Jony Ive polish and with all the hoopla around GTAT I have a theory why. We have Apple's precedent of every new phone having 3 things, a larger screen, thinner than the last and lighter than the last (even just slightly). We also have a lead designer spending an ample amount of his time researching watches for the new Apple Watch. The two things that bothered me picking up the 6 for the first time is how light it was and that protruding camera.
So let's follow a theory why. Jony is convinced by his new watch buddies that a premium product like the iPhone should have a sapphire screen like high end watches. Jony convinces Tim to pony up cash to get GTAT up and running for Apple Watch and iPhone screens made of sapphire. So Jony and his team set out making the 6 from the beginning with a sapphire class cover as a design constraint. One thing that we know about sapphire that would effect the whole design of the 6 is it is much heavier than the current glass screen. This places Jony in a tough situation, to keep with the Apple thinner, lighter, bigger he now needs to sacrifice weight alone in the body and battery to meet the so called "Steve Jobs" design iteration standards.
So the team does it. A sapphire screen iPhone 6 that is bigger, very slightly lighter and thinner than the current phone. Much to Jony's better judgment the only way to get to those criteria mean that the camera lense has to stick out. But in his mind that amazing sapphire screen will hide every other fault of the phone. And guess what else sapphire is, much harder than glass and not susceptible to bending...so prototypes are made, tooling ordered and orders placed.
Then the crushing blow comes to the design team, GTAT will not have the sapphire ready for launch due to either manufacturing, yields, finishing or whatever. Apple scrambles to get Gorilla Glass on order for the 6 to be able to launch on time. Jony for the first time in his career since Steve has to release a phone he is unhappy with since GTAT is not pressured by Steve. Losing the sapphire makes the phone too light in the hand, that protruding camera (which he tried to hide in photos) looks ridiculous from a design standpoint and Bendgate is born from a less rigid phone. Jony in a last ditch move to save face convinces Tim to move the Apple Watch launch up to the iPhone launch even though it's not fully operational. He removes himself from the iPhone other than the mandatory "the most beautiful phone ever" tagline and goes on and on about the research, beauty and design of his new Apple Watch.
I'll get the mandatory "Cool story Bro" and "I didn't read all that but I'll reply anyway" out of the way, what does everyone think?
