Bigger phones are popular mostly because they are a computer replacement for a lot of people. As we do more and more on these devices a lot people want the biggest screen they can afford but there will always be those that just want something manageable (to them). - Lee Peterson
Lee gets it spot on here, for a lot of people there only device is a smartphone and it makes perfect sense to have the biggest and best you can use. However there are a lot of people, myself and Lee included, that just want a device that gets out the way.
For a long time I have thought the perfect screen size was around 5", or a device around the size and weight of the iPhone 7. However people like myself have to accept that the world wants bigger whereas I’d rather put some barriers in the way to my screen time.
