Those phones are still _huge_ compared to the original iPhone.
The iPhone 4 was perfect at 115mm * 59mm and weighing just 137 grams.
The 13 mini was the last bearable iPhone at 132mm * 64mm and 135 grams.
Newer phones are simply too large and clumsy, and difficult to handle with one hand even for me as a grown man with fairly large hands. I don't want a tablet sized phone, I want a fully functioning phone that doesn't feel like a brick in my pocket.
Same! I want a small and not too expensive phone for typing and using on the go, fits in my hand and in my pocket.
And a (small) tablet for drawing and videos, it has less constraints in term of size, and can live in my bag.
The real answer to this is threat analysis: what are the realistic scenarios under which it becomes a problem. e.g. if Japan stops supplying ships a) how likely is that and b) could we just buy them from the Dutch instead? However, the stakes for getting this wrong are high.
