For those who purchased Thom Hogan's Guide to the D800 and D800E, he has just released a new update - Version 1.05. You should have gotten an email from him with a link to download the latest update, at no cost. The link is only valid for 30 days, so if by any chance you didn't get the email you might want to chase this down with Thom.
If you don't own this yet, I highly recommend it, to go along with Darrell Young's book. Thom covers a lot of the science and technology of digital imaging that are not unique to the D800/E by any means, but he makes them all relevant to these cameras. Very educational and very interesting stuff, especially if you enjoy learning how things work and why they work that way. For me, this basic knowledge has been very empowering and really helped me improve as a digital photographer.
