I was selected for a Pilot Program with iPads. I am getting TEN iPads for my classroom, with $500 iTunes cards for EACH one ($5,000 in apps total)! I am trying to pick out a case that will allow my kids to use them as communication devices. Does anyone have any ideas? I want one that ideally is A) less than $50 per case, and B) has a strap so they can carry it with them (but the ipad screen is still accessible) I AM SO EXCITED I CANT EVEN SIT STILL.
