I will trade levels of comfort for levels of safety with awareness.

I hate touching M's phone. I recoil in horror every time I have to try to do anything to help her. I hate the interface.

My first smartphone / PDA was a Treo. I've had multiple black berries. With and without the trackball and the keyboard and the scroll wheel. All the way up to the pretty fancy flat screen right before they tanked.

Simultaneously I had multiple iPhones. I was very comfortable with the midlife iPhone interface. Had them for years.

Then I started down the Android path. And as I said I watched them evolve and had my hands in the other guys simultaneously.

I know what I like and I'm sticking to it and I am not going to fall into an interface that makes me question every button I push. Every swipe I make. I recoil in horror.
