I’ve been having a problem with Google Docs recently. Their import engine is as strong as it could be. I’ve been sending a Word document back and forth with a friend; each of us making changes. When the last version arrived in my Gmail account I tried to view it as a Google document. The import engine could not decipher between the different versions of the file. Microsoft Word saves past edits so you can track changes to the document, but Google Docs got mixed up and included all the edits.
I’m sure they’ll work out the kinks at Google Docs, but until then I’m sticking with Word.
