I thought this was interesting. This subject has been discussed before on MobileRead but never in the context of actually eliminating
paper textbooks completly, nor, I think, in such an all encomposing way .... setting a date (only 4 years away), setting up a cloud computing network for schools, storing students homework so it can be accessed from any internet enabled device, virtual classrooms, etc..
The South Korean ministry of education has announced a ground-breaking plan to digitize all textbooks which are in use in Korean schools and thus completely phase out printed materials by 2015. This opens a huge market for manufacturers of tablet PCs, laptops and smartphones as the Korean education ministry has revealed it will spend US$2.4 billion on buying appropriate devices and digitizing content for them.
