As promised last week, the e-book is now for sale. For $25, you get three DRM-free versions of the book: PDF, ePub, and Mobi. The ePub format works on pretty much every e-book reader — except the Kindle, which reads the Mobi format. Apple iPad owners will be happy to hear that the PDF page size is almost identical to the hardback page size, so the PDF looks great on an iPad. (Kindle owners say the same thing).
So go buy the e-book now! And tell your friends!
