If you are trying options out and you want to go back to your original 
setting, you have to remember what your original settings were.  In some 
cases they may be easy to remember, or being able to reset your original 
settings may not be a big deal. But, there are plenty of cases where it will 
be a problem, especially if you are exploring or configuring unfamiliar or 
advanced option.  Revert/Undo is important safety net so users can feel 
confident about configuring and exploring the system without fear of doing 
something Bad.
