I have an iPhone 6s which links seamlessly with my iPad
Neither connect to my computer!
If anybody is really interested in why, send me your telephone number and I'll ring and dilate on the subject.
I have NOT had my iPhone very long (bought refurbished) and it does everything that I want at present (and lots of things for which I have no use!).
My iPad was also bought refurbished.
But if it's a decision between writing name and address on paper or buying a new telephone, I'll stick with a pen.
