I leave my iPhone at home because I like to compartmentalise my life.
I do internet stuff on a computer with a big screen because it is so much easier with a proper keyboard. Once I'm away from my computer, the internet is out of my life.
I take photos only when I'm in photographer mode.... with a proper camera not a toy camera with pin hole lens.
My phone is for SMS and emergency calls only.
I bought an iPhone and learned to use it only because I don't want to end up a dinosaur. It's a useful gadget like a swiss army knife.
