Microsoft released a fully functional version of Office 2007 Professional a few weeks ago. It's in Beta2 but very stable and it's basically as good as the final product. IMO it's far better than Office XP or 2003. If you're buying a new PC or just want Office Professional for free (Word, Excel, Access, Powerpoint, Publisher) this is the way to go. It's fully functional until February 2007.
