Aside from looking like an afterthought, the protruding camera will affect stability when laid flat, affect use of the 'spirit' level (you can't even prop the phone on its side because the sides aren't flat), and the ring around the camera will get bashed about if you don't use a case. The lens cover may well be sapphire but the ring around it isn't.
Then there's the battery argument. If you make the casing slightly deeper so that the camera doesn't protrude, then you will be able to squeeze a larger battery in there. Win-win.
I think you're greatly overstating the protrusion of that ring.
The back of the iPhone 6 Plus is a smooth aluminum, marred only by the protruding camera lens and an ugly set of of plastic lines at the top and bottom
The iPhone 6 Plus is the first iPhone that looks and works better in a case Ive been using Apples leather sleeve and it makes the phone easier to hold, evens out that camera bump, and hides the weird lines on the back.
Apple opted to essentially outline the top and bottom of the phones back with small plastic stripes where wireless radios can transmit signal. It just looks bad, like someone drew on my phone with a marker. HTCs simple, striped design on the One M8 is far better, and even Apples glass-strip-on-top-and-bottom approach on the 5S looked nicer.
Over the years, Apple's continued to fine-tune its reputation for building devices that combine solid build quality with a premium design. While these new iPhones generally continue that tradition, there are a couple quirks that are difficult to un-see. The first is the excessive use of antenna lines on the back. The two stripes stretching across the top and bottom sections enhance the look of the phone's rear -- much like the HTC One series -- but there are two unsightly lines that follow the upper and lower perimeter, and they stick out like a sore thumb. Secondly, though the phones got thinner, the camera module did not; the result is a lens that sticks out from the rest of the chassis, which increases the likelihood of the casing and lens getting scratched. [These] detract from the device's beauty, not enhance it.
If Apple has faltered anywhere with design, it might be that protruding iSight camera lens on the back, which sticks out a tiny fraction of an inch thicker than the rest. Its something that hasnt yet caused me any issue in daily use, but it does seem like a potential area for grit build-up, and it also means that the phone will be resting on its lens when placed face-up on a flat surface though thats somewhat mitigated by the use of sapphire in the lens cover.
The iPhone 6s smooth profile is broken by the slightly protruding camera lens (instantly fixed by slipping the phone into one of Apples new, sleek leather or silicone cases) and a set of plastic lines that run horizontally across the back and near the top and bottom edges. I don't particularly care for these design elements
[W]hile the iPhone 5S stood out in a crowd of Android smartphones with its chamfered edges and Leica-esque controls, you might not know the iPhone 6 next to the latest Galaxy S5 or the HTC One. And while the design is still impressive, some details feel a bit off. The bold antenna lines that run around the back of the devices and the protruding camera lens make the phones seem slightly less disciplined compared with the companys previous work.
I own a 3gs, 4, 5, and soon a 6+. Out of those, I have to say this is, design wise, my least favorite. The camera lens is a point off for sure, but the antenna lines are what really kills it for me. I get it, they are functional and to get the phone this thin a sacrifice had to be made. However, when talking purely about looks, well... it's not ugly, but it certainly isn't their best effort either. At the end of the day I think the 4 is still my favorite.
I like the overall look (round edges, anodized aluminium back, curved LCD cover), but don't like the look of the antennas and the protruding camera lens. Although I think the antennas don't look that bad on the space gray due to less contrast.
But like you said, nothing that can't be fixed with a nice case to cover up the back and raise the camera when the phone is lying down.
I just got back from the AT&T store to check out the new phones. I am still happy with my Space Gray choice since black looks classier but I was expecting the gray plastic to blend in well with the Space Gray aluminum. I was wrong. It looks more pronounced than the white plastic bands on the Gold model. It is hard to explain, but you can tell the gray plastic is...plastic...while on the Gold model, the white plastic looks more like a polycarbonate material.
Also the screen is a bit more hollow feeling than the 5, kinda like going from the iPad 3/4 to the iPad Air. BTW, if you research my post history you'll know I'm the biggest Apple fan in the world. Just wanted to convey some thoughts on the less positive aspects of the 6. Also wanted to give my thoughts on those who like me, thought the gray plastic bands would hide well.
The funny thing about it is I haven't even really seen the big difference in the camera, like it's not that much better.
