More that half of Danish municipalities have equipped schoolkids with Chromebooks -- but some failed to limit which services thay could/should use and so effectively send the kids' personal data out of the country, which caused quite the furor.
I believe Chromebooks will damage childrens digital education. Especially in that age you learn by experimenting and such a system isn't made for that. It is made to display something an equally digitally unqualified teacher wants to display.
Sure, schools cannot offer administration for the numerous IT related issues some systems might have. But that is a secondary problem.
