Ok, to describe little bit more my use case.
Current situation: I am solely using iphone 7 - web surfing, videos, photos, social media and after 1.5 year with only iphone I do think I want something more
Previous setups: I used to have macs but we can skip this,I jave no need for “real computer”, but I was bit experimentig with uos devices - I had two plus iphones (really liked the screen but aleays afrer year with plus phone I found it so cumberstone in the field that I have returned to smaller form factor), I had ipad mini 2 and liked it quite a lot (it was my go to web surfing device as i had macbook for something more).
And now: we have a baby so I bought myself better camera, so I am finding setup that would work. Probably iphone+ipad - iphone for live photos (but for some higher quality pics I will use fuji camera) and on the go device, ipad for home surfing, books reading, videos and some basic photography work (I am no expert, all I need is get pictures from fuji to my ios device, do some basic adjustments and save it to the cloud+if i find a way, get them to the nas). So, I do consider mini 5 as i really like form factor (not sure if any bigger ipad would be so easy to as iphone replacement at home) but I am not sure if screen is not too small for photos. And on the other hand, if somehow I find myself buying Xr/8plus, is not mini really to small to buy it as complementary to the big phone?
