It seems that Service Pack 2 for Office 2007 is now available for download from Microsoft. I am not sure if you can get via windows update yet, but it should be there soon. I tested the opening and saving of the Open Document format and so far it looks good. Now you can use MS Office and not be tied into a proprietary format any longer. It also has the ability to publish files in PDF format which should be helpful for those who do not know about any of the free pdf print drivers that are out there.
