Using the free and open-source productivity suite OpenOffice.org can be a godsend for those that don't want to hand over more money to Microsoft. Its word processor, spreadsheet, presentation, and database applications almost mirror that of the MS Office suite. However as you may have already noticed, there are some differences between the two. If you have been a regular MS Office user, the lack of some features and minor differences in OpenOffice.org and converting between the two formats can become quite bothersome. Just don't give up yet.
