I have had problems with this product and have reported the difficulties to Amazon. Seems others have had the same problem with the book freezing up, and locking up the entire Kindle. The search function freezes up, and if it works at all, takes many minutes to go to the page you want. Other times, it just freezes, and I've had to completely reboot Kindle to get out of the book, and I've also had to archive the book, or the entire list of Kindle books in my table of contents has become unreadable. Amazon advises they have contacted the publisher, to figure out the problems. As of 8/25/10, I would hold off buying this, and asking the Kindle people at Amazon from time to time, to find out if the bug has been fixed. Otherwise, I can't wait to get the product back - beats the heck out of hauling that big kahuna of a quad combination to church all the time, and the search function (when it first worked) was just fine.
