I certainly wouldn't embark on a long-term OSX/iPhone project without mastering IB.
It's obvious that your UI is easier to modify and update using IB than hacking it in and out of the view controller code.
Back to the original thread, I do give a little credit to Android to having the option of UI editing done inside of Eclipse. It's not perfect, it's a little hacky, but the concept of slapping down a UI element like a button, naming it, and then having it automatically compile and show up in the editor autocomplete is a powerful thing. The first time it happened it honestly was a nice surprise.
