Yet another approach to iPad books: this one from Push Pop Press, who’ve build a publishing platform that aims to cut production costs a little. (Via Wired). John Gruber had a good writeup of the platform in February - there are some impressive people behind this.

And yet given how much this sort of thing costs to produce and how small such things will be as a proportion of the broader publishing industry, books apps sometimes feel like displacement activity - a way for publishing people to distract themselves from the radical and dangerous changes in business models that ebooks will probably bring.
