It came into question as to why I don't use payments other than cash when I'm out and about. I took a look at myself. 
Who else nowadays uses a Nintendo DS to read Classic books (I do like to have them at hand even though I've read them perhaps three or more times) and what a handy pocket sized gadget! As small as a phone perhaps, oh hang on, I suppose I could get them all on my phone!
And look at a nice leather filofax to keep dates in order, there's something about writing things in it that appeals. It is larger than a phone granted, but I won't be swerved on this at least. 
I'm so old fashioned.
