Too much tech for children?

According to an opinion piece in the New York Times:

"More technology in the classroom has long been a policy-making panacea. But mounting evidence shows that showering students, especially those from struggling families, with networked devices will not shrink the class divide in education. If anything, it will widen it."

Is this too negative - may be. Be we really have to look at the research and not just accept the very effective and motivating promotional hype coming from big tech companies whose main priority is simply to sell their services and hardware.
