When the 14 Pro came out I bought one day 1 to replace my 12 mini.
I figured the size would be an issue, and I definitely didn't like it as much as the 12 mini. But the worst part I didn't even foresee was the weight. It was SUPER uncomfortable to use one-handed, I was constantly terrified it would fall out of my hand. I ended up returning it and buying a 13 mini.
The switch to titanium is a good move. Even barring the weight, while the stainless steel is certainly eye-catching and looks great out of the box, as soon as you use the thing it's covered in smudges, and infamously is prone to getting covered in scratches over time.
