For those who have been using unices for many years, it is difficult to remember the challenges of a switcher. I've been using Linux for 12 years, but I have constant reminders, because I'm a CTO, and have to support the end users who are coming into a new OS environment. When you, who have all this stuff in your head, trivialize the new users legitimate challenges, you are part of the usability problem, not part of its solution.
