I upgrade on every launch day. Admittedly it is more difficult for me to do so on S releases. Some feel these are the most meaningful upgrades but I am not one of them. This was honestly the first time I look back and think I should have just kept my 6. I don't notice a thing different between my 6S and old 6. Not from picture quality to speed and performance. I don't use things like hey siri or 3D touch so it's been a lackluster experience. I will most certainly get the 7, but I doubt Apple will be bringing me the features I have been longing for.
