Query: Microsoft Office Home and Student 2007

The only complaint I have about this product is that the Microsoft Word is not compatible with earlier versions of Word. (This may also be true of the Excel and PowerPoint). So, when I have to send a document to someone else, anyone who has an older version can't open it. If I would've known that before I bought it, I would've purchased an earlier version (probably 2003).
