* Security. By incorporating incremental advances in security and results from application testing, the 2007 Office system SP1 offers home and office users better protection against malicious software and potential threats to privacy

Here are my top picks that I think really make it worth to install the Service Pack 1 for Microsoft Office:
* When inputting calculations that should result in numbers 65,534 through 65,536, Office Excel 2007 no longer returns the display error of 100,001
* Office Outlook 2007 no longer closes unexpectedly when the junk e-mail rule is set to null.
* Items moved from an offline folder file (.ost) to a personal folder file (.pst) now display properly in the preview pane.
* When users try to open a presentation in Office PowerPoint 2007 from a Web site using forms authentication, the presentation will now appear properly.
* With Office Word 2007, users can now open and edit embedded objects that contain other embedded objects.
* Office Word 2007 no longer prints an extra page when users choose a printer with the duplex option enabled.
* Improved performance in Microsoft Office Outlook 2007 eliminates frustrating delays when opening large mailbox files and frees office workers to focus on important business tasks. The 2007 Office system SP1 makes it easier to open large offline folder files (.ost) and personal folder files (.pst) that are located directly on the user’s machine.
