"User Friendly" depends on the type of tasks that the user intends to accomplish, and the frequency of those tasks. The things that expert users intend to do are not necessarily the same things that beginner users intend to do. Essentially it is about the path-of-resistance between you and your goal. A beginner friendly UI might do X, Y, and Z. But complex tasks like scheduling X, Y, and Z, automating them based on other events, or even performing them rapidly in sequence, are likely to be given a higher path of resistance.
