Query: Excellent book but not the Kindle version

Almost every page has formatting errors, typos, errors of various kinds, some minor, many serious. It's hard to understand how the publishers have the gall to charge $15.00 for this. There are some omissions that render the text incomprehensible; I can't even be sure just how much text has been omitted. Prof. Smith has written an excellent book that obviously required much work and careful attention to detail, but his electronic publishers have sold him out. This book makes me want to turn in my Kindle.
