As we get further into our second year as a Google Apps for Education district, (and Google continues to refine their product), I see the advantage of using Google for all of my office needs over MS Office is the integration of most of my online life that Google affords me.
We do not have the Office 365 tools that level the playing field, so anytime my ultimate goal is to share, collaborate, or publish to the web, I open up a web browser, not my Microsoft Office task wizard.
The presentation below very briefly reviews most of the Google Apps products that we have enabled for our district, and the bulk of the slides are filled with common teacher scenarios that can be served more efficiently or effective by a Google Apps product.
