The last thing education needs is lock in (content and application walled gardens) and a high entry cost (expensive hardware requirements).
Education should be free and open.
Education is not free and it certainly isn't open. You pay for it with your taxes; the government decides what goes in the books and curriculum and unions don't let us create a competitive marketplace where bad teachers evaporate from the radar and truly good teachers compete and make two or three times the money they make today while providing a better education. Much like anything that government touches, the system is a mess and our competitors are eating us alive.
