The good news is that Novell has promised that it will release code for OpenOffice that will support the new file format, but it'll be at least another month or two before that's a viable option for end users, and there are still many corporate users who will be stuck since many of them don't have the option to use or install OpenOffice. Out of the box, Office 2007 saves documents in 'Microsoft Office Open XML.' The saved file formats are docx for Word, xlsx for Excel and pptx for PowerPoint. Although we have enjoyed reasonable (but still far from perfect) compatibility with our Windows Office brethren for some time now, that all changes with Office 2007 for Windows, which uses a file format incompatible with Mac Office by default. Delayed or not, the next version of Microsoft Office for Mac can't come soon enough for those who have little choice but to stick with Office in corporate environments.
