Just bought the book. This is more of a comment about Hyperink: It looks like a really nice platform, and seems like they do good marketing too. The only confusing part with the purchase process initially was that they only show iPad and PDF highlighted as available formats. Nook and Kindle look greyed-out (??). I was just hoping to get an ePub, so wasn't sure if I'll get one. Eventually it gave me a much clearer list of options to download from: pdf, epub and mobi. Why not simply showing those options with the same terminology in the first place??
