In South Korea, the days of students lumbering around with backpacks full of books could soon be a thing of the past.

A new government initiative aims to replace all physical textbooks with eBooks distributed via the cloud and on school-provided tablets by 2015. The country plans to spend over $2billion developing the paper replacements. It's not clear who will manufacture the tablets, but South Korea is, of course, the home of the mighty Samsung.

Stateside, tablets and devices like the iPod touch are used in some schools on a more sporadic case-by-case basis.
