Oh well since this is pretty much a rant all you want topic, guess I'll put my 2cts as well. As you all know, I can't stop myself from doing that.
although yes, the progress with the smartphones have enough utility in it that it actually helps to have one.
edit: the use i have for my phone are a local map(saved onto storage), viewing novels and mangas, listening to music and watching videos. and to some extent browsing and chatting when theres a wifi hotspot.
And the phone to me is purely for gmail, whatsapp, skype, sms, music, audiobooks, being a point and shoot I carry about me, and googling some technical terms when I need to read something in a foreign language with the occasional finding myself on the map once every other month.
Now, if you noticed, there's nothing in that list which would greatly benefit from having a large screen, or at least it's not necessary. So why the fuck is it impossible to a get a nice non-gimped version of a phone that has a smaller screen than 4.7 inches.
Anyway, I know how you like to pump out studies in all your arguments kita, so I'll bite. Here's an article that references a shitty study that shows people requiring far more time to operate larger phones compared to smaller ones.

1st, everyone is going on and on about how easy to brake phones are... Well, guess why? It's because you're carrying with you something that has roughly 100 square cm of face surface area while being some 8 mm thick. I wouldn't mind too much if it was a 10x10x0.8 plate steel we were talking about, but it's just not and that's not a recipe for something sturdy.
And what do people do with phones like these? Put them in fucking cases so they'll be sturdier, beating the point of a thin phone in the first place.
How about you get me something that is just bellow 2cm in width, that should about make the whole structurally sturdy enough to where people wouldn't need to bother putting it into a case and I could finally have a battery that would fucking last me a whole god damn day of use. Having a power bank in your bag should not be a necessity for anyone who expects to use a phone for the whole day.
