I disagree. There are major trade-offs in terms of convenience and practically that goes beyond any personal preferences. You need to unfold the phone (an additional action) to do basically anything, while currently, with standard smartphone you don't. You also need two hands to operate the device, while currently, you can do basic tasks (i.a. check stock price, view notifications, answer whatsapp messages, etc.) with just one hand. I don't need any user to report that to know it is true. Samsung and others are already releasing their 3-4th generation of foldable devices, and I still do not observe major shift to this type of devices, which in some way might be indicative about the customers overall interest. If foldable phones were so great, these devices will be flying off the shelves, and yet, after few years of availability, their market share is still slim. Between a foldable iPhone, and the rumored super-thin iPhone Air, my gut feeling is that the Air would be a bigger hit and definitely my personal pick. Obviously, this does not mean that there aren't many people that are happy to live with the trade-offs of a foldable device, for the sake of the additional screen real estate.
