OpenOffice vs. MS Office for Education?

dbrian asks: "I work in a large high school district where there will be some discussion on whether or not to purchase another term of 'Software Assurance' for MS Office licenses on thousands of computers. This seems to be an ideal opportunity to promote an alternative such as OpenOffice. It will not be an easy sell, even though OpenOffice should more than satisfy all curricular needs and save the district lots of money; like many other districts we have political and cultural 'challenges'. So, I ask you, have you been successful in moving your education or business organization from MS Office to OpenOffice? What were the pros and cons from your migration? What advice do you have in selling this to tech coordinators and administrators who are not enlightened by Open Source?"
