Our May '08 to November '08 study of adult U.S. internet users found that of all participants who used Google Docs or Google Spreadsheets, 68% also used Word at least once, indicating that Google Docs has yet to be considered a stand-alone product by most of its users.  By contrast, only 26% of OpenOffice users also used Word during the 6-month study.
