The PC world in this time frame lived with less human concepts of computing and claimed that their way was correct and better for serious work. We Macintosh users knew how much baloney this was and we held onto our good and correct dreams for humanity. But they all fail in the areas of what I call the Macintosh dreams.

Messages are incomprehensible.
Dialogs and menus lead you to wrong choices and unintended errors. Software crashes too much. It loses data. Files get corrupted. Checkboxes are used when radio buttons are called for.
