I covered the book in a course for graduate students at Purdue during the Fall semester of 2000. I enjoyed going through the material, which is concrete, important and interesting--and the students did too.
The book is written with great care: all the details can be followed, the notation is a model of consistency, and there are almost no misprints.
The problems and tutorials were not only interesting, but fun, as was working with CoCoA (except when it tended to crash too often on my Macintosh, until I learned how to avoid certain pitfalls). All in all, it was a very nice educational experience for all concerned.
