I suspect most people who have owned iPhone 6/7/8 Plusses are people who don’t own iPads. For them, the Plus is an iPad Lite. I understand this. As for me, since I do use an iPad which seldom leaves my side, traits in a phone I look for are compactness and inobtrusiveness. I rarely pull my iPhone out of its holster because most interactions that would require interaction with the phone can be handled by my Apple Watch. This means that the iPhone X, barely larger than my current iPhone 6, is an attractive size for me.
