Stenography is very fast, but can't replace a normal keyboard (i.e. you wouldn't want to use MS Word with it or code with it). Also it has a large learning curve and can vary from person to person.

On the other hand, you don't have to move your fingers around - they stay in one place. And it makes possible a very large number of key combinations (when using both hands) that can be used as optional shortcuts for typing common words.
That's not typically the case - http://en.wikipedia.org/wiki/Chording_keyboard.
