BLOWBACK: Not everyone in South Korea is welcoming the digital textbook revolution with open arms, and school officials are pulling back on plans to go completely digital by 2015. These second thoughts may be related to a recent government survey that found 7.9% of children between ages 5 and 9 years old "addicted" to the Internet. (And oft-reported stories of online gaming addiction don't soothe concerns either.) Given that the country is often heralded as a global education model, the move signals to some that a full headlong rush to digital may not be the wisest choice.
