Let me start by saying that I LOVE the Fluent UI (“Ribbon”). I was not so sure about it at first when started using Office 2007 but after a short time I was pretty happy. Now in 2010 you can add your own buttons it is even better.
I have to admit that in Project I was SO used to the menus that it has been tough. But the Office user ed team came up with a VERY cool set of interactive guides.
