Kno - the digital textbook system

I have just been sent this link to Kno by someone in my professional network. The information on the home page drew me in straightaway ..

"While no one was looking, someone revolutionized the textbook, higher education, and learning itself in one crazy, bold move."

Yes, it’s a digital textbook. Yes, it’s a whole new ecosystem. Two
spacious panels. Touch-screen interaction. A fully-stocked store. Video.
Note-taking. Sharing and community.

Kno is everything a textbook was. And will be.

Take a look! What do you think?
