I believe that's not true. The topaz-book I read at the moment has sometimes a very poor quality: Sometimes mathematical symbols or whole parts of formuals are absent (I compared it to the extract of the print edition on Amazon). The reason is that in topaz they probably use scanned parts of the book, and it seems that there are some problems concerning quality control for topaz-books, I believe. PDF is an exact copy of the layout of the original book with high quality - but poor for small e-reader screen. If I use pdf-reflow (e.g. on my sony) the mathematical formulas are completely destroyed. So I have to use topaz, if I want to use the ebooks.
