Certainly not - tablets have their place, but mandating any tablet would be just as silly as requiring "calculators" should be standard in every classroom. A more sensible approach would be to look at the broader needs for the school: i.e., laptops or netwbooks for some classrooms, tablets for some classrooms (or available for checkout), and possibly BYOD capabilities so students can use their phones or personal tablets to access the school network.

I personally don't like the iPads much as they tend to hurt my fingers more than a standard keyboard, however I am sure in time I will get used to them. I don't believe they have a place in every classroom however. I think the iPad could be more easily broken than a computer or laptop especially by students in lower years or with behavior management issues. While they take up less room I personally think something a little bit more unbreakable is better.
