How many hours does the author think it should take to set up an iPhone? If they want every toggle and every accessibility option presented at device setup, with enough explanation of what each one does and how to use it, it’ll take at least 2, probably more since the elderly tend to use technology slower.
You know what the author didn’t mention? That with any Apple device you can go in for a 1:1 session or a class on usage, and the people running them will walk you through everything. They’re also good at identifying people struggling to use the device in various ways and know about all the accessibility options, which in general are more plentiful and much better supported in iOS than Android.
My mother got an iPad after years of owning only android devices, went in, and not only did they walk her through it, but they let her know that a new iOS release would be coming out soon which would change a few things, and invited her back to a second session after that change if she was at all confused.
