Office2007 is in public release---but double check the description at whatever site you are looking at--- and updating it would not be free. Some things to consider:
1. Unless you do collaborative work, the 2007 does not provide major increases in functionality.
2. The new user interface will require a learning curve if you are used to older versions of Office.
3. The file structure is different from prior versions,and there are unanswered questions about compability.
Most companies that depend on Office applications will not upgrade for some time.
