Once I had to change the battery on a car I used to own, I could see the battery, but I didn't know how to get at it. there was a plastic cover that did not seam to have any fasteners. I went on line and not only found that answer but found a video showing how to do it. Just rip it off by the way it snaps in and off no problem.
At my high school we use schoology with our ipads for content deliver to our students. Any student can ask me question through an assignment when at hoe or at school, and I send answers back to them using my Ipad. I think it will continue to be used in education, and classes are going to become more and more online.
