We found the switch to first the iPad & then 4.0" iPhone screens to be greatly aided by IB. The fear (?) that's always keep us with IB is that eventually the device screen widths are going to increase -- tools are supposed to help with such issues, why not trust that IB will lead you there?
As a side note, I learned to enjoy Android layout systems. It was all a big mystery until I could finally test layouts interactively within the latest Android Studio [0] GUI. Although I'm not sure if I'd rather have a similar XML schema for iOS, I'd bet that the JetBrains folks might have already thought about doing this for their AppCode tool[1].
