Like the fancy looking graphs and other features in Office 2007 but don’t want to learn the new (is it still considered new at this point?) ribbon interface, the UBitMenu plugin may be up your alley. It doesn’t replace the ribbon toolbar, but instead creates another tab that tries to mimic the menu system of Office 2003. You still get all the formatting features found in Office 2007, but in the previous interface. It’s free and covered by a Creative Commons License.
