I love parts of Office 2007 - Outlook is fantastic, and Power Point is worth upgrading to, But I hate the ribbon. I want a Classic Editionm so I can be productive and not have to figure out where the Office Team have moved things. I hate the ribbon.
I found out a cool trick today Control+F1 hides the ribbon. It's NOT a full answer to my hatred of the ribbon, but it does help get the Ribbon our of your face when you are just typing away. Of course, just clicking on a menu brings the Ribbon back.
