Office 2007 Will suport ODF
ODF, Open Document Format will be supported even by Microsoft Office 2007. Just to be sure, not included in Microsoft software, but There are already finished filters (on sourceforge) which will allow to open and write ODF together with Word. Support for another Microsoft office programs such as Excel or Outlook will be finished soon. But that doesnt mean all documents will be ok, there are some features in both formats, which arent included in that second one. Hope some time there will be era without problematic Microsoft software, and Open formats will rule. Or at least they will have support directly in Microsoft products, no that somebody will have to create format converter.
