I agree, although Darrell's book is very concise I have found it disjointed appearance wise on the iPad Kindle app, whereas the D700 and D7000 Kindle books were fine. As an example, I get the title of a new chapter at the bottom of a page instead of on a new page. This maybe a temporary thing as it's only just been released and they may publish an update. I think I'll write to Darrell and inform him of this, won't be his fault but a kindle or ipad/publisher problem.
