If you purchased Office 2007 after March 5 and before September 30 2010 you are probably eligible to upgrade to Office 2010 at no charge. But you only have until October 31, 2010 to request your free upgrade. You can find the details here.
Office 2010 adds many new features especially in Outlook. However, there are a few menu changes that can be frustrating at first. File formats between the 2007 and 2010 versions are the same. We would suggest Clients that are eligible go ahead and upgrade.
