I don't doubt that some portion of the iPhone user base really loves the 4.7" iPhone, but I think the author's premise is based on the assumption that the device that people use is the device that people love/want. Note that if this assumption is incorrect, it could be wrong in either direction: there may be a lot of people who are using 5.5" devices and would prefer a 4.7" device, but there could easily be more people who own/use a 4.7" device and would prefer a 5.5" device and simply haven't upgraded yet.
