Earlier quoted context omitted.
Obviously, I'm not a school admin but I would wager replacing a fleet of cheap Chromebooks with Macbooks (or any big brand Windows machines) would not work out cheaper, or less burdensome, or anywhere close.
The issue is they where marketed and sold for an environment where they don’t work.
Then came the iPad, less said about that the better.
Chromebooks are many times better than this and have the added benefit of being cheap and, dare I say it, disposable.
