If you haven't yet upgraded to the latest Microsoft Office, don't do anything without test-driving OpenOffice.org. With a familiar-feeling interface, the Microsoft-replacement application is easy to pick up and matches Office's major functions application for application.
For instance, OpenOffice.org makes and edits text documents, spreadsheets, presentations, databases, and drawings. It also has templates, collaboration tools, and support for macros. It can export content to Google Docs and it is compatible with Microsoft Office documents, so you won't be stranded when sending and receiving attachments.
