I go from office 2003 office 2010. One is for or one is ccntre for those great practical result of this, will not be disappointed by the 2010 version. He certainly has put on weight with all the new features. The whole is sometimes a bit confusing. I use Office for a long time and the 2010 version remains a powerful and enjoyable tool to use. Outlook I found easier to work on the 2003 version.
