Microsoft's Office 2007, and to a lesser extent Vista, is bringing a radical change to the desktop user interface. The Office Fluent UI feature -- the ribbon interface -- introduced in Office 2007 is Microsoft's attempt to help users get more out of Office applications. For nearly two decades, apps have relied on the menu interface to collect and expose features, but as programs' capabilities have ballooned, the menus have gotten overloaded. Software developers have tried various supplements, such as Office 2003's approach of hiding infrequently used menu items automatically, and Adobe's use of floating multi-tabbed feature panels -- approaches picked up by other developers as well.
