More generally, I do think that the Mac app is currently easiest to use when you have lots of hierarchical organization to do. I personally tend to add a lot of info in the iOS apps, then structure it on the Mac.

We've learned a lot by doing our first 3 iPad interfaces, though, and I'd agree that OmniOutliner is probably the first place where we'll need to apply those lessons and step it up a notch. (Not being sure how to nail a touch-based outlining interface is one of the reasons we didn't tackle OO right out of the gate, actually.)

As we figure this stuff out for OmniOutliner, we'll eventually be able to take those lessons back and apply them to OmniFocus. That kind of learning takes time, though; we didn't want to delay OmniFocus until we had figured the answers out. Current app represents the best job we could do at the time - suggestions welcome while we figure out how to bring you a better one. :-)
