dual-screen tablet had a pretty tough road since its debut last summer. The educational device was plagued by shipping delays and low pre-order numbers, and by February of this year, the company effectively threw in the hardware towel. A few months later, Intel plunked down a bunch of money, so that Kno's dreams might live on in the designs of other manufacturers. The company's software plans are becoming a reality now, as well, with the release of Textbooks, which brings some 70,000 discounted educational titles to the iPad. The free app lets students read and organize texts, affix annotations, and communicate with study partners, offering creative new ways to pass notes in class. Press release after the break.
