Bought the 12 Mini on launch day and loved the form factor so much (which is surprising because I had only purchased Plus/Max models as soon as Apple started offering them). Then the hype of the 13 Pro got to me. I needed the ProMotion, better camera, and big battery.
Now, after using the 13 Pro for a few days, I just can't handle it. It's too heavy and feels like I'm dragging a brick around the house. Comfort, weight, and portability is far more important than a marginally improved camera setup and screen. I am returning my 13 Pro for a gorgeous 13 Mini in Midnight today.
