"I don't use the word "radical" lightly. The entire user interface, the way you do things in these familiar old programs, has been thrown out and replaced with something new. In Word, Excel and PowerPoint, all of the menus are gone - every one. None of the familiar toolbars have survived, either. In their place is a wide, tabbed band of icons at the top of the screen called the Ribbon. And there is no option to go back to the classic interface."
