Having had RSI for a while I can't tell you how much I've wished for interfaces with point(/look) and speak UI. I literally haven't found a single case in which I couldn't quickly dream up a superior version of an existing UI. Overall I came away with the conclusion that look-and-speak is probably the most deeply ingrained user interface there is. Perhaps the only one that you could argue is truly intuitive, as it seems to be genetically hard-wired. On top of that modelling UIs as representation of hierarchical state machines is an astoundingly simple and elegant way to model such UIs; even allowing you to leverage persistent data structures to do amazing things.
