I have an issue with the amount of laughing/snickering/and general off-task behavior during study halls. I wouldn't mind as much if the students were rockin' it in their classes, but generally the ones that complain of too much work, didn't remember to do the HW, etc. are the ones that I look out on and I am confident that they aren't using their iPads for good use.
Plus, if/when I do catch them doing something like watching "Fail compilations for October 2015" then what am I to do? Take away their iPad? that they may have work to do once they get home?
I would LOVE a technology that can intercept and show what they are seeing like some computer labs I've worked in have.
