It's nice and pretty. Now on an ipad3 it's slightly laggy. Transitions are slightly slow, and every interface element feels a bit "almost there" in term of responsivness. Then, downloading the pdf and viewing the same content in a native viewer is liberatingly smooth, fast, responsive, albeit without the animations and custom controls. This demo seems very apropriate to experience the gap between "html5 and JS everything" and "single purposed and optimised" presentation formats.
