Microsoft Office 2003 or Microsoft Office 2007, which one is better?
Niether. Open/Libre office.
Office 2010 FTW! If not, then 2007. I dislike 2003 because of the various menus. The ribbon is fair easier to use.
Office 2010 is better nowadays.You can access all the settings,features
very easily that all have in office's productivity suite.It also has
more features than their previous versions.
Office 2010 if you ask me...
As for the choices you presented it doesn't really matter, both are fine. If you can get accustomed to the Ribbon interface go with 2007, otherwise it is 2003.
