Apple is offering a free 30-day trial of the office suite, available here. The trial includes the whole iWork package: Pages '09 (word processing), Numbers '09 (spreadsheet) and Keynote '09 (presentation).

The new iWork.com will allow users to distribute data online so that anyone can view the iWork files, regardless of platform. Colleagues can also download PDFs to work on the files locally, so that users can do work remotely. 

iWork.com beta is currently free, though Apple plans on charging for the full version. Until then, try it out!
