GoogleApps/Advantages-Disadvantages of GoogleApps over traditional Office Apps

Personally I do not use GoogleApps enough to say whether or not I like them. I use the Mircosoft Office package and have used that for as long as I can remember. I would like to explore these Apps more to make an informed opinion on them. The advantages of the GoogleApps: they're free, its easy to access, students can work together in a very easy manner, and it has all of the types of programs the Mircosoft package offers. Disadvantages include the Google Chat function, at Hamburg High School they are beginning to use the GoogleApps and one of the concerns was that the students would use the chat function in class to talk about things not revolving around the class discussion. While the GoogleApps does have the same sort of programs as Mircosoft Office they are not as advanced and may not be as well used as the MO system. GoogleApps include: Mail, Sites, Calendar, and Docs.
