"Drop Microsoft Office for Google Apps or LibreOffice"
The thing with dropping MS Office, is that there are programs that will not work with things like Google Apps, LibreOffice or OpenOffice. For example, you're in an Architectural program that is able to export to Excel... but it will not even recognize this to be installed, and will not allow you to use this feature. Exporting simply to a file location with a .csv or .xls format is not an option. Now, the fact that other programs need to have this ability is another topic. But my point is this...if you're an IT Admin, don't roll this change out in your environment before testing your applications that integrate with MS Office.
