I have a Sony camera with an SD card. One of my computers will read the SD card, one won't even recognise it. I have no idea, these electrickery things are a law unto themselves.
I still have a film camera that I use sometimes. I use Filofax diary instead of electronics, and I won't have a smartphone. I would like to have radios with knobs that you turn instead of little electronic buttons. [/Rant over]
