Users often find themselves using shortcuts, and chicklet buttons as a way to avoid using the menuing system itself. Unfortunately, they failed to exploit that opportunity and have added little to the party when it comes to menuing. Fortunately, they are small and adaptive, and corrected this. Because Be is still a small company, I am hoping that they are agile enough to adapt and improve, and their UI gives them an area to do so. By this I would mean Solaris, Irix, X-Windows, Motif, and other Unix based UI's I have worked with.
Menus seem to be no better.
