Like humans, some are smarter than others. I would certainly say an iPhone 6 comes under ‘smart’. We have both just moved from the old SE (iPhone 5), me to an, X (10), Marj to an 8+. Both hand me up’s from my son and dil. There is little of the extra smart features we use, but the face recognition is great, so long as you don’t have a damn mask on. But the speed of use and quality of the camera are a world of difference. Oh, and screen size is bigger on a physically smaller phone.
I think it’s excellent that there is so much choice available to suit people’s needs, (or lack of needs). Apple miss out on that as they don’t seem bothered with the basic phone demand. Although I am with Apple, I think it is the Android open source project which drives innovation.
