When we started talking about the ribbon everyone knew it was a huge bet. It is nice to get some props! Here is what they have to say:

"Innovation? Microsoft? Yes, we were surprised, too, but the Redmond giant's latest upgrade of the world's most popular productivity suite introduces several new features that revolutionize how people work with documents (see our review). The most striking change is a "ribbon" at the top of the interface that replaces the traditional cascading menus and taskbars, and can expose functions you never knew were there. Through the suite's handy new Live Preview feature, you can see how formatting changes, for example, will affect your document prior to your making them."
