A lot of people still don't like the look of the Office Ribbon, but many have grown to understand it and actually use it better than the old menus.
That's because it's a horrible, inefficient shiatty interface and I will continue to hate it as long as it exists. all the core applications that come with win7 now use the ribbon, and as a result I don't use any of them. They even ruined MS paint, an incredibly simple application, with this stupid interface. As for Office, I now use OpenOffice, which is nearly identical in functionality but keeps a useable, traditional interface.
