If you're buying the phone for improved camera, you'll be disappointed. I currently have the 6s and S7 Edge, but I have to say Samsung kicks Apple's ass on photo, video, and audio quality. The S7, S7 Edge, and Note 7's camera is better. Note 7 has battery problems but they're getting that fixed. If you plan to vlog with your phone, you can certainly tell the iPhone 7 sounds muffled. Both are waterproof to some degree if that's the excuse, but Samsung does much better with video and audio quality.
I don't know why Apple can't include OIS on the telephoto, which is more needed than just the 28mm one. Maybe to have something to upgrade on the 7S? I also don't understand Apple's fascination for their bokeh explanation in their presentation. Samsung has a F1.7 Aperture, which can do very beautiful bokeh, not to mention they allow more camera controls.
I also don't even know why Apple need to remove the headphone jack. The phone has the same thickness as the previous version. There's only one speaker on the bottom, and the microphone doesn't take up that much space. Just more BS excuses to sell their wireless junk headphones. And by junk, I mean Beats.
