Look and feel of any phone should be personal preference. but the Software, performance, speed and ease of use of the iPhone 7 is top notch. in terms of hardware, nothing much has changed except the home button and the camera.
Updated and positive points of the phone- 1) performance and speed 2) Camera 3) speakers 4) water resistant 5) Storage 6) New colors
Negative points- 1) Overprized 2) Design-(Nothings changed revolutionary)
Overall if you are iPhone user they the iPhone 7 is not a game changer but for the rest of the people it is an awesome phone overall but overprized.
