If you do one thing over and over again, then an intuitive UI with informative notes is unnecessary, but to classify those of us who have to use multiple systems with multiple applications to accomplish various tasks as "average users" is demeaning. A good UI benefits users at all levels. Your attitude is the reason that even IT professionals (like myself) tend to leave Linux for their Apache and MySQL servers. For day to day computing the Windows or Mac UIs and applications are more productive because of things like "informative notes".
