I just watched a documentary about an elite Chinese high school, and it was certainly eye opening. I know you won't find any of this surprising...
I don't recall seeing a single computer, laptop or otherwise, in the entire program. China's best and brightest take notes using plain old pen and paper. Imagine that! And no student is allowed internet access -- not on campus, at least.
I highly doubt that any of these students spent their first years of life watching a screen or playing infant/child video games (a la V-Tech or LeapFrog). In any case, these students certainly aren't spending their days downing soda and playing video games -- the opportunity to attend this high school is so valuable that good nutrition is considered essential, and any activity that takes time away from studying is out of the question.
Meanwhile, in the good old U.S. of A., public libraries are resorting to video game tournaments in order to get kids in the door.
