You meet them online, but they’re a vocal minority. Especially when a smaller phone means a smaller battery and worse camera system, two of the consistently top priorities for consumers.
Could be a larger demographic thing. Tech enthusiasts tend to have lots of devices(tablets, portable computers, etc.), so they tend to like the smaller form factor phones since they can always use their tablet/laptop when the small phone is limiting. Those people are also the ones you see in these kinds of online communities. For a lot of other people though, they’re getting the big phone and then not having a personal tablet/portable computer at all. Those aren’t the kind of people that hang out online and talk about tech stuff though.
