I Am Looking For Reviews of Gmail Outlook2003. Please.

Does anyone have any opinions on using Gmail Outlook2003 together? I am doing a paper on the different Outlook versions and I still need a few opinions on this program. I have had really good input on all the outlook programs, They all seem to rate very high on the scale when it comes to how easy it is to configure, and also that is is so easy to use when it is installed. Usually you get a few that are really negative, so far I have not gotten one report that is really bad. Which means that it must really be a great program.
