Two things stand out:
1. The setup process should have a heavily simplified mode right at the beginning. It may not be simple for Apple to decide what to exclude from the standard setup process, but there are several obviously time consuming, annoying and unnecessary steps in it. A lot of behaviors with side button double click, camera button swipe, etc., should be off by default.
2. There should be a very short test on finding out the accessibility needs of the user (to the extent possible, because some people may not know how to follow written or spoken instructions).
These are not just for the elderly, but also for many others who have accessibility needs, who lack knowledge about gadgets (or can’t be bothered keeping up with changes in interfaces and disappearing physical buttons), who just need something simple that serves a few actions (like phone calls, video calls, taking photos, viewing received photos and videos, etc.).
