Last week, the Business Analyst at work sent me a link, Office 2003/2007 Assistant
What the link will show you is the differences in commands between Excel 2003 and 2007, so users can learn how to do things with the Ribbon.
Excel 2007 really should be used when hitting SQL 2005+ OLAP Cubes, but companies are reluctant to upgrade because of the “jolt” of learning the Ribbon. Not anymore, with that assistant you can find out how to do anything you could in 2003 (not just with PivotTables – with anything)
What this means, is that there are NO MORE EXCUSES to not upgrade to 2007. Hey, with Office 2010 around the corner – March 2010, you better get ready for it, and there no time like now to upgrade from 2003!
