Query: office 2007

This is not a good office product. It has been revamped to look cleaner, but it is much harder to use and to navigate through then office 2003, which is what most people use. It can not be opened by office 2003 without a patch, so things that I send to others can not be read. I find it horribly frustrating and wish that I would have waited to find Office 2003
