So far so good! I have to admit a few things about it...
- The additional weight makes the device feel more substantial and better quality. I don't mind the added bulk at all, and think I actually prefer it honestly.
- The camera, in my opinion, doesn't really feel drastically different...I can tell that the sharpness seems improved, and it seems to focus a lot quicker than the 6 Plus did, but I feel like the 6 Plus handled artificial lighting situations better than this one does, and that indoor photos, while better quality, seem a bit darker than before on the 6 Plus (something that is easily remedied using the native editing tools for lighting). Not sure if anyone else is noticing this too, but I'm getting a lot of lens flare around direct lighting sources where the 6 Plus isn't...
- Phone performs better...no doubt about it. I guess that should be obvious with 2GB of RAM and upgraded internals/processors. Not sure about battery life, but so far, I really like the snappier functionality of this phone. The 6 Plus seems a hair slower across the board...nothing substantial, but definitely noticeable.
- I LOVE the vibration/haptic feedback feel on this phone. One thing I always felt about the 6 Plus was that the vibration being the way it was made the device feel cheap in a way...like poorly constructed. This new functionality feels quite solid...well polished even.
- 3D Touch is very cool. So many different things that it is injected to...and it feels so fluid. I can't wait to see where they go with this feature set...because so far, especially with the sub menus, it just flows like water. It's starting to feel MORE fluid than OS X, and that is a first for me as I've always preferred the computer based OS vs. the mobile one, but now that gap is definitely closing if not equal to me.
- iOS 9 flies on this new device. You can tell this OS was made for the 6S/6S Plus. I can't even imagine using iOS 9 on a device previous to the last generation...comparatively, it'd have to feel like garbage honestly. Sucks for 5/5S owners because that device is still a great smart phone...but I think I'd stick with iOS 8 if I had one.
- Going back to space grey was a great move for me...I realize I truly prefer the black glass vs. white. I don't think I'll ever buy a white iPhone again.
