This is important for parents to note. Teach your child about computing on a RaspPi where they'll actually learn real computing and not a walled device with a download button. I know they're convenient at a restaurant...etc, but they rigidly enforce instant gratification without much learning involved. I guess though it isn't super different than a Nintendo if taken with moderation, but I'd argue most of the games are less complicated in scope...more like slot machines than something with an engaging story and strategy. They also have an infinite amount of games at their fingertips instead of I'm bored with "x", time to go play.
