I disagree. Kno was not focused on making education better. They were focused on making a bad business model a bit lighter, and more attractive on an iPad. This could be a nice business, but does not represent the type of mindset that would offer VCs the payoff that they need.

Textbooks as we know them are a bad business model in today's education system. Useful, but wasteful. Teachers assign an expensive book. Then students are only required to read 40% of it. Right there, you can see a serious disconnect and waste of resources.
