Well, definetely worths 1.99. This is the first app for iPhone allowing you to test 3D page turning feature available exclusively for iPad. Interface: Its just simple and beautiful. You have main info and options under your hand. It has some reverse side of coin: item downloading view is a bit ugly(especially on iPad), devs need to redesign it. Usability: You can redefine tap zones to vertical or horizontal. As for me, "dead zone"(where pages dont turn, instead you have some info about book and some options) is a bit small. Instead of showing options I sometimes turn the page. Rendering: iPhone version is just beautiful! iPad version is a bit ugly, you see these polygons and non-real shadows. But these bugs are nothing comparing to readMes advantages ;)
