I am starting college in less than two weeks. My school recommends that all Mac users use MS OFFICE 2004 for Word and Powerpoint and Excel and whatnot. My school also sells Office 2004 for $75. I was planning on buying it in two weeks when I went up there. So should I buy it in two weeks or wait for the Mac verison of Office 2007 (when is the release date?) ? Is it possible that if I buy OFFICE 2004 now that I will be able to get an upgrade to 2007 for free? Thanks.
