Remember when everyone had the same Nokia (or at least one of a few very similar models) and so you could borrow anybody's phone charger without worrying about compatibility? I still have one of those models - black and white screen, no camera, no internet connection, chunky buttons that I can press without having to look and see what I'm doing, battery that lasts for a week without charging.
Maybe I'm becoming a luddite with age, but I've never been able to get on board with smart phones or tablets. I don't need to be connected to the internet when I'm out and about, I hate touch screens and when I'm using a computer I like a nice, big screen. I'm firmly in the PC age still.
