I think Scott is more suggesting layers to replace NSCells and custom drawing areas within views. For example, I have a sort of vector drawing app for Tiger -- it has one big "canvas" view that does all the drawing and hit-testing and so on for all the art objects stored in the model. I'd guess that vanilla CALayers could probably replace half the code in that canvas class.
