The problem with interface builder is that it only exposes some properties and others you have to set in your class anyway. Why can't I set the background image of a view in interface builder, for instance? With RubyMotion you get to roughly lay out your controls, and then you get to use the interactive interpreter for fine-grained adjustments. See around the 5:30 mark in the getting started video for an example.
