Microsoft Word 2007's document types, interface, and some features--very nearly every aspect of this word processor--have changed. With this update, Microsoft Word 2007 becomes a more image-conscious application. New picture-editing tools help you deck out documents and play with fancy fonts. Bloggers and researchers may also benefit. It's easier to get a handle on document security, but those who only need basic typing features may not want to relearn the interface or deal with the new file formats.
