I also prefer the ribbons, but a real power user of hierarchical menus doesn't click through them. The menus in Windows used to have the first character underlined: this is a shortcut. File->Save could be accessed with an incantation like Alt+fs. The real power of the old menus was remembering the discoverable shortcuts and flying through the menus without using mouse, somewhat similar to how Vim works.
