In the Android Market began to sell books

As reported by Engadget, in the Android Market appeared a book section (so far with one book); judging by the fact that I do not see it myself, it is now launched only for some countries. Of great interest is that, according to Engadget, when the address market.android.com/books appeared before the official launch of the section, the market.android.com/music and market.android.com/movies appeared along with it, which suggests about the imminent sale of music and movies.
