I can adjust my SIM card size too with adapters so is not a problem for me to switch between devices.

Currently... I'm using Lumia 1020 as daily phone. I'm a photographer so it is difficult for me not to carry a mobile phone with very good camera. But often still I use my N900 which I consider the best mobile I've ever had.

Very very soon I'll have Jolla (we must support our cause ) and I hope that I love it.
