As a warning I have only used the kindle version, as this was my first experiment in using the kindle for a reference book.While the content and examples presented are great, the formatting on the kindle suffers from several problems, mainly when presenting formulas. They mistakenly have C instead of subset operators, leave off multiplication dots between numbers, etc. When there aren't mistakes in the format they suffer from some fairly obviously low res images for the formulas.I cannot compare this with the print version but I have not ever found a print book with all of these problems.I would be curious to know if this problem exists in many of the books or its specific to only this one. In any case be warned.So on content I give this 4 stars. On ebook presentation I would probably give it 2.
