As an example navigating a list directly with my fingers is much, much faster and more convenient than navigating it with arrow keys (physical or on-display ones).

Navigating a 2D space with my fingers, just dragging around or pinching to zoom, is also much, much faster and more convenient faster than than doing the same with arrow keys (again, either physical or on-display ones).

And navigating through the OS and apps, either through lists and 2D spaces (websites, images, maps, videos, etc.) is a lot more common than copying files around on phones. 100:1, probably. Again, some techie/advanced functionality was lost at the start, but the time and frustration savings from those basic yet intuitive features heavily outweighed their loss.

If you don't agree with this, I guess you either haven't tried pre-iPhone smartphones or you just have a very unorthodox opinion and I'm not very keen to continue this conversation.
