PDAs/iTouch in clinicals?

Has anyone ever had a nursing school where they flat-out refused to let you use PDAs or iTouches during clinicals? I was talking to a friend earlier who's applying for the program I hope to enter in the next two years (recently started my pre-reqs) and just wanted to know if anyone had. Can't find someone to ask at my own college. I want to find out because if they allow them, I need to start saving up for them now, haha!
