Let's move things here.
The biggest hurdle to innovation of this sort in public education is the "one-size fits all" curriculum development model. All the teachers should be doing the same thing in all the classrooms, etc.
This links to all of the deployment guides, white papers, and videos.
A lot of schools just hand teachers iPads and expect them to deal with deploying and managing them. If it were IT professionals instead of teachers trying to deal with iPads in classrooms, I think a lot of programs would be more successful.
I think technology like the iPad could be the way to overcome the one-size-fits all model. Self-leveling and personalized tests can customize a learning experience in a way that scales, allowing students who do well in a particular subject to excel and move ahead, while not alienating those who are in the back. This could also allow the teacher to focus on tutoring students who need the most help.
I think khanacademy.org is a good example.
