No, I’m not in the same position. I love my iPhone and would hate not to have one, my life is on it! I decided very early on that having paid so much for one it was jolly well going to work for me, and it does. If there’s an app for anything I’ll have it. Going supermarket shopping I just take my car keys, bags and the phone. I pay for everything with the phone. I have maps for the whole of the UK, bird identification apps, all my music, all my photos, emails, my Kindle library... If, as it looks likely, the government decide we shall have some kind of vaccination passport it will be on a smart phone app. Smart phones may not be necessary but they are certainly very, very convenient. Why in particular do you not ever want to get one and why do you worry that you might have to?
