The content of the book is of a high standard, unfortunately it has not been laid out with an e-reader in mind. All the Chinese text appears as images, this makes it impossible to use the built in dictionary to define individual words or characters. Additionally, using the book as a source for vocabulary is also made difficult by the fact that words or phrases can not be copy-and-pasted into a vocabulary application. The Chinese text is also very unclear and zooming in does not help. If the issues with layout are resolved this would be an excellent learning resource.
