By 2014, all of South Korea’s elementary-level educational materials will be digitized, and by 2015, the entire school-age curriculum will be delivered on an array of computers, smart phones and tablets.

The makers of the Kno tablet made a pretty good case that if we’re going to replace textbooks with their digital equivalent, we need devices with something like four times the screen territory of the iPad.

This move re-ignites the age-old debate about whether or not students learn better from screens or printed material. There’s also the issue of whether or not devices with smaller form factors are as effective as current textbooks.

This is potentially a huge windfall for Samsung. Students and governments are a captive audience. As long as their hardware and software continue to improve, they might not have to compete with Apple; this is a whole other niche.
