The ability to share documents and create forms with Google Apps is very useful. I have used it in the past to allow students to collaborate on a class assignment and it could be applied for making notes for team meetings or other curriculum projects during the summer when it's hard to get everyone together. The forms seems like a great way to ask short response questions to an activity or gather information (if you didn't want to use the SmartBoard) from different groups about errors they saw in an lab, things that went wrong, or interesting things they noted while we were working together. It could also be used for feedback surveys to get a feel for how the students feel like their progressing at the end of a grading period for example.
I will surely be using this in the fall.
