We just picked up 7 iPads at my school that teachers will be able to check out together for group work. I was just wondering if anyone had a recommendation for a nice case for schools (high school), and if there is anything out that is almost like a mini cart for <10 iPads. I was thinking if we had a nice case for each (like the Gumdrop) we could really just stack them, or have some kind of small shelf unit on a cart to hold them. With only 7 I figure we will just have a power strip that they all plug into. Is there anything like the Gumdrop that is cheaper? $350+ for cases seems like it is a lot.
