I've worked through at least the first book of this version and it is a very nice intro to the material. One large annoyance I have is the mistakes. I was trying to follow the proofs closely and there are some errors both in the diagrams and in the text. Many of these are called out in the intro so I found myself flipping between the corrections section and the pages to make sure I had a very clear idea of each proof. This can make some of the later proofs a bit cumbersome to follow since they all build on one another. So if a later proof is built on proofs that contain mistakes it is distracting and a lot of page flipping.
