What are the differences between Microsoft Office 2003 Professional and Microsoft Office 2007 Professional?

You can't use 1 click answers with Office 2007

one of the main differences is the GUI (graphical User Interface) it now has tabs and ribons insted of tool bars and menus. it has added a LOT of new features. it almost looks like they spent all of there time working on office 07 and no time on vista

I HIGHLY recoment office 07

Office 2007 contain a number of features above ms2003. it has a good looking with the help of Great GUI. it contain feature which are different from 2003.
