Visually I much prefer the squared off edges, but I agree. The 14 Pro is the first iPhone I’ve regulsrly used a case with because I just cannot keep hold of the damn thing—when the phone angles as I reach across the screen I guess the lack of surface area touching my hand means it sorta just pops out. I find it really bad ergonomically. Flat edges with rounded corners seems a nice middle ground.
What I really want is a Pro Mini. I bought a 12 mini because that year the hardware gap between Pro and not was very small. The battery sucked ass but it was a dream to hold.
