The lastest 1HDC had pages filled with some excellent eReader designs. We saw everything from paradigm-changing concepts to designs aimed at hiding the technology and preserving the look and feel of a common book as much as possible. The winner (and first to submit) is Kinl with the eScroll concept--an ultra-mobile device that challenges the obvious form factor.
Some notables: Special mention should go out to Yo! with his excellent bar-raising rendering of a leather bound i-something named nu*book. Callosum's exploration of eye tracking functionality could have had a clear shot at winning with a better rendering; (the bar was definitely raised for presentation quality this go around). KasinChan approached the problem from a student perspective--combining the best of low- and high-tech.
