Quick Take: Word 2004 for Mac gets off on the right foot with the improved Track Changes feature, which adds color-coded notes for comments and text deletions on the right side of the page. This is an enormous improvement over version X. The app also gets Smart Buttons, a feature borrowed from Office XP that among other things, gives you the option of keeping the source formatting of pasted text or matching the format of your current document.
