Google Cloud Connect is a Microsoft Office plugin released today by Google. It has been available for testers since November, but it is now generally available. It syncs a user's Office docs with their Google Docs, and adds a toolbar for sharing documents right into Office. We've been asking for offline access for Google Docs for years now, and this is a step towards that.
Google Cloud Connect is available for Windows XP, Windows Vista and Windows 7. Office 2003, 2007 and 2010 are all supported.
Google has slowly but surely been turning Google Docs into the mythical Gdrive, and we've been tracking that progression.
Google also announced today its 90-Day Appsperience program - a way for those curious about Google Apps to get a chance to try it out for a "nominal fee" for 90 days.
