I feel like Chromebooks would be a better choice anyway. Much more educational content including Pearson's is available on ChromeOS than iOS.
Agree. In academics, students should have a good sandbox to do whatever they want, live the consequences of their actions and learn from it into adulthood. iOS does not provide this.
Give the kids the most most open device out there. Have the teachers freak out their kids are more talented than anyone in their teachers union. Create the next generation of capitalists bucking the system they represent.
That grows the country.
