Apple could've thrown copy and paste into the first iPhone, but they didn't because they didn't feel they had it right.
They might be in the process of actually designing an interface for formulas that actually expands the reach of such functionality. You know, something that the "I'm bad at math" crowd could actually dig into, make use of, and learn within.
If you release a basic not-that-hard-to-implement version of the functionality, it's WAY harder to drop in a new, innovative model afterwards. I think there's a lot of sense in waiting until they can get it right, if they're planning on doing something different with it--which, judging by the other UI departures they've made, I wouldn't be surprised if they are.
