I love the snap photo and video options on the Mac Books. I can see student groups using this for project checkpoints and progress, or filming their progress. I also love the idea of being able to sync apps to the I-pads for students. I would use this with Geography practice and extra challenge programs for GT kids or kids done with work early.
Management has been a big issue for us with our school COW. My teaching partner and I have always been somewhat strict about sign out and checking them for sign in, but can't necessarily rely on other teachers to have the same system. I love that these new devices will be ours, and thus, tracking improper use will be confined to our classroom only.
