After having completed reading Mr. Young's book from Amazon.ca I found that I benefited from the information so much that I would like to have it on my iPod for easy access when traveling. I know I will enjoy having the knowledge portable as I decide to refresh my memory on various concepts and settings. I wasn't to optimistic about format with such a small screen. I found the book at the iTunes store and was delighted once downloaded that there were so many features - highlighting, book marking, easy navigation through the book to pin point a topic. It is colorful and the pictures are easily visible. I have not offered a review here of the book but I left one on Amazon.ca and made comments previously on the Nikonians website. Obviously if I want to copies of the book I find the book valuable.
I have also been reading a PDF version of a book on the camera by another author but I find it tiresome to navigate through the book and it is not as well prepared. It is a great source of information but has a lot of tedious detail which is of little interest to me i.e. historical background and intricate detail of technical operation.
