Google Drive is pretty slick. It allows you to collaborate, edit on the fly, and create documents and easily share them. The problem is, most of the time somebody in your organization will end up using a Microsoft Office product and throw a wrench in it all. You see, Google Drive's editing abilities don't mix well with Microsoft Office files.
Since Microsoft Office is the standard for business documents, Google is trying to alleviate any problems a bit by offering up a free copy of Quickoffice which is very compatible with the various MS Office format. If you're a Google Apps user, grab it free from the Google Play link below.
