Go to an Apple Store and see them all side-by-side. What makes those devices what they are are the high end devices on the next table over.

The advances very much do trickle down. Whether you would personally buy it or not.

That's a non-answer. I'm asking people who buy high end phones why they pay extra. A phone with faster processor and more memory can't be the only reason people pay extra for these devices, which is all I'd get from comparing specs.
