Getting into the book, but they didn’t do a good job of converting it into an ebook. Skipping around from chapter to chapter as you’re instructed to is difficult, and the charts are abysmal, almost unreadable unless you magnify them significantly using your iWhatever. It’s like someone just took the printed version, ran it through a scanner, and voila! E-book! Going across town now to the last big book store left to buy this in paperback, which is what I’d wish I’d done in the first place.
