Other than the interface and usability enhancements, is there anything *new* that is worth the upgrade price? I'm pretty content with Word 2003 and would consider myself a power user as far as keyboard shortcuts and getting around the user interface and I use it primarily for basic word processing so I'm looking for a compelling reason to chunk down some money.
I'm also a fan of Nota Bene for academic writing etc. Does the new version handle bibliographic resources and footnotes better?
