Yup.
I used to think this would be the biggest upgrade since the 3Gs to 4. Now it is one of the worse like from iPhone 2G to 3G or 3G to 3Gs.
Dual front speakers and water-resistance is nice. A copy from HTC One and Sony Xperia Z from over 3.5 years ago. Things from camera, speed test, display (still stuck at same resolution), and design hasn't changed much.
Truly one of the worst since 2009.
Worst to Best
1. 2G -> 3G
2. 3G -> 3Gs
3. 6s -> 7
4. 6 -> 6s
5. 4 -> 4s
6. 5 -> 5s
7. 5s -> 6
8. 4s -> 5
9. 3Gs -> 4
The tick years when we from s to an iPhone 4, 5, and 6 were the biggest upgrades both designs and features. The 7 is the smallest jump dealing in a tick year.
I still prefer the s models as I prefer the strongest twin. But this 6s to 7 (aka 6se to me) isn't even that drastic like 4 to 4s or 5 to 5s were. Camera, performance, display, and design have generally been a stalemate.
