"Every part of the ribbon can be customised" Afaik, that is not true. I tried to do that just today with Outlook; I cannot remove the ribbons (ribbon groups??) that I don't ever use, Send/Receive for example. (When you're connected on a high speed connection, what's the point of that? But you can't get rid of it.) Likewise, in Word I'm pretty sure you can't remove things like the Mailings ribbon. (Mail Merge? How 1980s...) Also, if I'm not mistaken you can't add commands to any of the existing ribbons; you have to create a new one, even if you only want to add one command. It's been a long time since I've used a version of Office with menus (sigh...), but IIRC you could change every part of it. So on the contrary, if my memory serves, the menu was far more customizable than the Office ribbon. (I don't know about toolbars, I never used them.)
