I'm beginning to think product evaluation is an afterthought with their development team...
I'm pretty sure half of them were playing with watches this year and "oohing and ahhing" at the (mediocre) iWatch instead of the now secondary iPhones... I mean so much of the new iPhone just seems to be about what they think people want rather than what they actually want and practically there are issues that should have come up in testing...
"Thinness" is great and all that, but not when the camera has to stick out or when people are begging for more battery life. Moving the power button to the side when the top was still fine made some sense until you put it opposite the volume switches so now you're always accidentally hitting them together as your hand naturally tries to oppose the force of the press on the opposite side - something that should have been picked up in early hands-on testing...
The whole bending thing, were they really in that much of a bubble when initial concerns about the iPhone 5 came out that "making it thinner" somehow didn't set alarm bells ringing - it's probably a minor issue but we won't know for a while, what it has done is give them terrible, front page press in many places (yes, it was the Daily Mail's top story on their site yesterday!)
The software features - well nearly all the new "innovations" don't actually work yet, that's absolutely terrible from Apple, Pay (as well as being US-centric) doesn't, the health app doesn't, iCloud drive doesn't. It's all a bit of a shambles and seems like we've been given the product 6 months early. And now this stupid, literally stupid update - WTF is going on!?
That said, my iPhone 6 works fine, didn't do the update.

I'm happy enough with it despite the rant, but I know it could have been so much better, I was already on the fence before getting the 6, now I will probably make the leap to Android next upgrade, the competition is ever-improving and the freedom from iTunes (PC version at least) would be liberating...
