As an engineer who expects to travel a lot, I was delighted at the idea of getting a kindle textbook. Fortunately, I tried the free sample first. I have to ask if anyone other than me has even looked at this. There are no chapter markers, making navigating the book a nightmare. The contents pages are badly formatted; whatever they used to transcribe the book has picked up all the problems as chapter markers, meaning the contents table has the full text of all the exercises and solutions in the book in it! Finally, there are no page numbers, a must for when you need to check a reference. This merits zero stars.
