Windows: OffiSync, the Microsoft Office add-on that syncs your documents to Google Docs or your Google Apps account, now offers a way to edit and save documents that you're working on with collaborators, as well as save Word-specific documents to the cloud.
OffiSync makes a lot of sense for businesses and groups working online together, especially through Google Apps. We named OffiSync to the top slot in our Top 10 Google Apps Marketplace Apps, and for good reason — it basically bridges the gap between working in Word or Excel and having access to those documents through Google. With the latest update, OffiSync now makes it possible for others to edit the documents you're working on in Office, even at the new real-time pace, and still let you save changes and see updates in your desktop copy. You can also choose to save documents with picky Word-based formatting in their native Word .doc format to Docs' 2GB of storage space, rather than have them converted for generic Google Docs use.
The collaboration edit features aren't free, but if you dig OffiSync, $US12 per year, or $US30 for a lifetime, doesn't seem like highway robbery. OffiSync itself is a free download for Windows systems with Microsoft Office.
