Excuse me, what on earth is non-obvious about that?
When enumerating the alternatives to the pinch-gesture (the awkwardness of which becomes obvious within the first few days of use) then you end up with a rather short list of 10-12 items - and that's counting rather esoteric ones like a physical jog-dial.
Apple chose double-tap, just like anyone else in their right mind (other than Sony) would.
If that's not textbook example for a trivial "invention" then I don't know what is.
