My issue with the statement is two fold: 1) "Any given" really isn't the same as "every". It's vague and ambiguous, and generally means it happens often, but is not a useful measure of incidence. 2) A deployment of this number of devices + custom software will have problems, that has to be accepted. One problem, without knowing what it is, really isn't enough to say the thing is a failure. In fact, it's not even close. Is the problem that someone has to restart their iPad? That the content freezes? The content is inaccessible? The content is incomplete? The Wi-Fi goes down? The teacher's materials aren't working? We really have no idea, and that kind of comment in this kind of story is adversarial and unnecessary.
