The Kindle version is unusable because (i) there is no possibility to navigate to the Table of Contents (incredibly bad!), and (ii) there is no way to navigate to a specific page number. This has changed from the 2013 edition, where with "Go to" both of these options were available. The publisher has allowed the product to deteriorate - sorry for you, Hugh!
I am returning my purchased version to Amazon - and hope that the purchase cost will be reimbursed.
