Well, that oversized Kindle didn't become the textbook killer Amazon hoped it would be, but at least one country is moving forward with plans to lighten the load on its future generation of Samsung execs. South Korea announced this week that it plans to spend over $2 billion developing digital textbooks, replacing paper in all of its schools by 2015. Students would access paper-free learning materials from a cloud-based system, supplementing traditional content with multimedia on school-supplied tablets. The system would also enable homebound students to catch up on work remotely -- they won't be practicing taekwondo on a virtual mat, but could participate in math or reading lessons while away from school, for example. Both programs clearly offer significant advantages for the country's education system, but don't expect to see a similar solution pop up closer to home -- with the US population numbering six times that of our ally in the Far East, many of our future leaders could be carrying paper for a long time to come.
