Sadly, I agree
I am currently in the process of designing educational software for the iPad, aimed at schools, so I have a vested interest in disagreeing with this article. Unfortunately, I think that most of what it says is probably all too true. But, given that schools do, like it or not, seem to be blowing huge sums on iPads my attitude is that the best I can do is to try to help make that decision work as well as it possibly can by writing useful educational software.
