Instantly reintroducing the basic bulk problem of lenses, which is what smartphones freed people from schlepping around. Even for free, it would be a no thanks for me.
Photography aside, my decision to buy an iPhone 13 Mini was driven by size. I did not want a larger device, which would have made redundant my current Case Logic shoulder bag that originally played house with a Walkman. Now, though, having realised - quite definitively - that I will never print again, the convenience of iPhone photography is overwhelming, in which case, a larger device suddenly has a tangible value that renders that of the ancient case’s original function but a romantic conceit.
