You will find that the phone has very little drama attached to it. Everything works, and it works exceedingly well, and the UI does it’s best to stay out of your way when you’re not using it. You may find it boring at first (e.g. because you can’t customize the UI up the wazoo), but you get used to it quickly. Soon, the phone just feels like a part of you.

BTW, good choice with the 13 Pro Max. I have it, and it’s been a rock solid device (it’s almost an insult to call it a phone. It’s a pocket computer that can make and take phone calls).
