I don’t get the assumption (not just in your comment, all over this post) that engineers and programmers are more likely to appreciate the changes.

I’m a programmer, apple devices have had the cpu grunt to run ssh or vi for ages. Therefore, I don’t really notice much generation to generation. I wonder if it will ever catch up to the Raspberry Pi in usability.

I expect a photographer, or maybe someone who opened big spreadsheets, or a social media person, or one of those coffee-shop authors, might be more likely to notice the difference.
