Yeah. I can buy the pdf, and later down the road download an updated copy when they fix it, but with the book that's not the case.
I like to have physical books, but $50 is a pretty hefty price tag for these books, considering the errors within. Considering that you can download updated PDFs, it really would be nice if they would release the PDF before sending it to the printers. There was a page and a half of errors and mistakes posts caught in the first 24 hours of release. Face it, gamers find errors, mistakes, and continuity issues more than proofreaders and editors do. When you are focused on finding mistakes of one kind, you might miss the others, and that seems to be the case here.
Had they waited, even a week, they would have 4 pages of posts to go through, fix the mistakes found, include the omissions, etc. Knowing that, I would gladly preorder the book, but knowing that the physical copy will be identical to the pdf I have, I really don't have the money to spend on this book, until such a time that it's complete and/or fixed.
