Yep. Huge kudos to the author for making it available, but the PDF does feel sloppy with all the bright colors and images. In science textbooks, less is more.
Compare this to the very latest edition of Stewart's calculus, which now uses even more pastel, subdued colors for diagrams.
It was a really elegant book, reminiscent of other classic Springer Undergraduate Mathematics Series tomes.
Lots of distracting color, highlighting, and boxes were added, which IMHO make the book less clear.
Obviously, the content is still great.
