I have more concerns about Google Docs than Google Drive. While files can be moved around and used pretty much the same offline as online, the same cannot be said about the use of Google Docs for collaborative document editing. If you're trying to de-Google your life, what is a sane replacement for Google Docs in a collaborative team environment where you can have some confidence that you won't lose all your assets?
