Buttons on both sides also completely breaks the ability to use the volume rocker buttons as a camera shutter -- 'oh let me quickly grab my phone and take a pictu--- nope, I hit the sleep wake button, sorry'
I hate that iphone 6 and onward design decision ... (design-wise pretty much everything after iphone 6 has been a regression imo, although this one looks the best that any phone has looked in a long time -- aside from the notch)
