This reminds me of something (much less substantive and important) that I have been realizing after buying my first Apple computer recently (I held out for a long time). Things like the trackpad and cable wrapping system are so amazingly intuitive, once you figure them out. However, I am so accustomed to sub optimal design, that I had to be shown how to use them both. This may be a case where sub optimal design is a net win, but ensuring that the pilots must stay engaged to at least a minimal degree.
