See, I still use a filofax for addresses and things- which dh thinks is mad, and I have a paper calender on the fridge. I write lists, and really only use my phone for texts and calls. I have a lot of apps on it, but can live without them. I dont use it to pay for stuff. I'm a luddite.
Dh would be like someone had cut off his air supply if he lost his phone.
