No one I know "produces" content on an ipad but it's fine for HN comments or management emails. So maybe that's what we want to teach, not sure.
In theory I suppose the lesson is that if you are a "regular" user, IT is brutally unhelpful, and put your content on removable media or cloud storage.
This is not such a bad lesson, and the kids who care about owning their data will eventually figure the other side our for themselves.
I still think using general purpose computing devices in general education has value, mainly because then the kids who don't see that at home will get a chance. When you do it's like the whole world changes if you're made like that.
