Intel has long been cozy with the e-textbook developers at Kno, going so far as to license their hardware and preload their software on its own tablets. The chip giant clearly wants to take that relationship further, however, as it just acquired Kno outright. While Intel isn't providing the terms of the deal, it's not shy about revealing the motivations -- it's determined to grow its educational content library, which now includes over 225,000 titles thanks to the Kno deal. Not everyone is happy with the new alliance, though. TechCrunch has discovered that Kno founder Osman Rashid turned down a chance to join Intel after disagreeing with the bigger corporation's focus on international rollouts over concentrating on North America. While that's a significant loss, we doubt that Intel is complaining much. The buyout still gives it a rich educational content ecosystem that could help fend off rivals like Amazon, which recently bought TenMarks to bolster its own schoolroom cred.
