I guess NeoOffice has a Windows version, though I was hoping for something smaller to download.
I think Tacit was assuming you would be running Windows under VMFusion or Parallels Desktop in compatibility mode where you can move freely between OS X and Windows apps. NeoOffice does not have a Windows version
which is why I recommended OpenOffice.org which does have a Windows version. If you are running in compatibility mode TextEdit will handle most Word .doc files and it is already installed as part of OS X.
Granted NeoOffice and either the Windows or Mac version of OpenOffice are a big download, but they offer excellent Word compatibility along with the Excel and Powerpoint compatibility.
