Question for the Group

Charlotte (Canada) has a question:

Hi Ben,

I have a technology question for the group.  Our school just bought a class set of Blackberry Playbooks. (not impressed)  I would like to buy one ipad for my class to use as a document camera.  I have to justify this expenditure and I was looking for more ideas for this ipad.  I know a bunch of you use an Ipad.  Can you give me more suggestions as to how you use it in the classroom?
