My sister got hers today through her 2 year upgrade (so replacing her 5). I was at work when she got it but she text to say she really didn't like the feel of it at all. I asked why and said she thought it felt a bit cheap (she got the normal 6) and she just wasn't particularly 'interested' in it.
When I got in I asked to see and she just pointed to the floor where the box was, with the phone in it! I asked why she hadn't set it up and she said she didn't think she wanted it, was gonna think it over.
I've had a quick play with it myself tonight, not a fan. But I didn't like the 5/5S purely because of the metal body. I don't like how cold, hard and rigid it feels in the hand (why I opted for the 5c, which I love), but coupled with the thinner body I think this feels like the iPod touch line. It's not a bad thing, but it's not what I'd personally want or expect from the newest iPhone.
That stick out camera is the biggest problem though, really un-Apple like, design wise. And the back of the phone is hideous. I think it's the worst design yet but of course this is just my own personal opinion which I think I'm allowed to have, but judging by some responses, I'm prob not entitled to.
I'm not surprised my sister isn't interested. I don't upgrade until The end of October, but now I'm not sure what to do as I was pretty set on the 6 until I've had a hands on.
But yeah, agree with all you say OP.
