Andy Ihnatko has recently switched from an iPhone to an Android phone for a few reasons, not least of which is the availability of larger screens on many Android phones.
It's a valid point. Industry analysts (what do they really analyze?) have been calling for Apple to release larger screens on iPhones for some time.
It's not as straight forward as they pretend though. Is a larger screen just a scaled version of the current iPhone (same resolution)? If it is, then Apple must address image quality concerns since it may no longer be a "retina" display. If the resolution is increased to maintain retina quality, the platform is fractured and development becomes more difficult. Apple may believe the current losses to Android based on screen size don't justify the difficulties.
I find discussions on screen size interesting -- the same user that wants a large screen on their phone may also want a small screen on their laptop for different reasons. A small screen laptop is usually a low weight laptop and the technophiles I read and listen to in podcasts will cite weight as a major concern.
I prefer a small phone that fits in my pants pocket. I do not wear tactical cargo pants like Andy Ihnatko... I don't think I know anyone who does. When I've seen someone carrying a Samsung Note, I don't see them putting it in their pants pocket. They are literally carrying it, like a tablet. For my laptop, I prefer large screens. If I were a 9 year old girl, the difference between carrying a 3 pound laptop and a 6 pound laptop might matter to me, but I worked out a bit during and after college, so that extra few pounds really doesn't impact my day.
