Software on the other hand, seems to go in the opposite direction. Instruction are extremely vague and expect the user to just intuitively know how the program is supposed to work. I often run into statements like, refer to the help file included with the software. Unless you need to know how to start (which you have to do anyway to get the help) the program, the help you are looking for will not be available.
I guess there aren't enough law suits for software companies to include all the information about their products.
