The Genera terminal, or "listener" was a real eye opener for me the first time I used it. It can display rich text and images, has mouseable elements like buttons and editable forms, and has a powerful incremental online help system. It's almost like a kind of scrolling desktop. The thing I really liked was that the console output was independent of the input line. You can start typing in a command, hit <help> and have the (rich, hypertext) documentation appear in the console above where you are typing in. You don't have to delete everything and type man foo like in Unix, only to have the man page disappear when you quit. Simply in terms of usability the Genera listener craps on any Unix or Windows terminal I have used.
