I would agree with you before Apple switched everything to gestures. Any time I now have to help a family member out on an iPhone I get extremely frustrated. Does the interface want me to swipe, long press or do something else? There are no real hints. Extremely irritating.

I miss the three physical navigation buttons that phones used to have. Yes, they took up a bit of space but they were also unambiguous about what their navigational function was.

I despise my work iPhone for the gestures and the screen lock canceling a call if it's not picked up yet, but turning the screen off if the call has been answered. Nothing more annoying than pinging someone by mistake and then calling each other with perfect timing so you both get the message that the other party is already in a call a couple of times.
