Interesting comparison.
When my youngest son was about 20 months old, he had an iphone as a toy. He couldn't read, he couldn't talk, but he could make it do things.
Very slightly older he was using screwdrivers to take phones apart. Now at 13 if something doesn't work, he fixes it.
He now will only have Android
He started with Canon, and now uses Panasonic M43.
My second oldest (final year at university) has an iphone.
He started on Canon, and still uses Canon.
He wouldn't know which way a screw goes to loosen it. If something doesn't work, he looks for someone to pay to fix it
