I used to only do things with Word, Outlook, and Powerpoint (I don't use the other office apps as much) that I couldn't do in Works or outlook Express....

But since I got Office 2007, and use the ribbon, I now know how to do a bunch of stuff in those apps (especially in Powerpoint) that I never knew before. I know you can do a lot of the features in 2003, but 2007 is just so much more intuitive, once you learn how the Ribbon works. Much better than sorting through 20 "Main Menu" options and a host of Dialogs.
