You have a literal internet connected computer with any function you could care to name, interactive touch screen display, full sound with headphones being provided by the student.
The situation we have now is that there are few apps that are suitable for a classrooms, even fewer which teachers would be allowed to use and none which are endorsed or included in the curriculum[1].
Meanwhile students phones have no central management unless by parents using a specialist app, are not automatically locked down to appropriate use during school hours, meaning they just get used for messaging and inappropriate stuff.
There is no reason that a students phone couldn't become the world's most amazing educational tool the moment they walk onto school premises - the world just hasn't caught up yet and probably won't for a while.
[1] I don't know this, but I'm sure they're providing iPads or something if they're actually doing anything around this.
