Well, OK, I don't live in Houston and publishing a media-rich, interactive ebook isn't exactly rocket science. (Although, for someone who usually makes his living with technologies that harken back to the Rennaisance and beyond, it can sometimes "feel" rather Buck Rogers.)
Everything has been checked -- images are all in place, the text has been proofread (thrice) for typos, all the videos run, and all scrolling sidebars scroll. Apple has approved the final manuscript (all 155 pages). Sales begin in 51 markets* world-wide on October 15. (That's where the "T minus 30" came from.) And pre-orders begin TODAY!!!
