Like the OP, I just came back from the store to have a peek. Nobody in our family likes the new design/size. My wife says she will stick with her 5. My daughter would stick with the 5, but since both her phone and mine have developed some weird camera problem (a tiny smudged region appears both in the screen and in all shots - and, no, it's not a smudged lens), she'll be upgrading to the 5s. I just gotta have the better camera and Apple Pay - otherwise I'd stay with the 5s too.
I really don't understand Apple: it makes the most successful phones in the world - all of which are 4" or less. And then it goes off and builds these Android-looking phablets at 4.7"+. Doesn't it realize that *some* - or even many? - like a compact device? It seems to have bought the "people want bigger screens" press/analyst criticisms of the iPhone hook line and sinker! Not saying Apple shouldn't have produced a bigger phone - I totally agree that there is a huge market for them - but why did they have to produce TWO of them and NO phone at the previous size?
About the looks: in the past, when you saw someone using a smartphone, you could immediately tell if it was an iPhone. if you covered up the logo on the 6, you wouldn't be able to tell it apart from a bunch of Android phones.
I'm sure I will get used to the 6...i just gotta focus on the new functionality, I guess.
