As a teacher of the Thomas series for years, and now a user of the Foerster text, I don't fully understand the basis of some of these comments. It seems to me that the new text embodies many contemporary techniques, and it hardly seems that it is dominated by "oldfashioned, out of date ideas." The course differs dramatically from the calculus courses I studied in the 60's and have taught in the decades since, yet clearly it does embody critical, traditional topics as well. None of the older texts referred to relied heavily on graphing calculator techniques, had major emphasis on numerical methods, required much verbalization of understanding by the student, incorporated group learning activities, included regular exploratory exercises, or included such topics as slope fields and Euler's method. Most likely the Foerster book, or any other, is not the "Bible" of calculus for the next decade, but having done a thorough search / review of available books last year, I found it to be an excellent alternative for these transition years of reform in calculus education. It seems to me to be an attractive compromise between the outofdate, symbolic manipulative texts and others that are ready to leap ahead and immediately abandon all traditional topics. Especially in these years when the AP test is steadily changing, essentially requiring high school students to be able to do it all  traditional and contemporary  from my limited experience (with the first four chapters, so far) Foerster is working well. From the teacher's standpoint, working with this book is very different from using older ones, and it is apparent on a daily basis in class that it demands of the student much more conceptual understanding and nontraditional, nonmanipulative techniques. With the exception of the few topics that have been eliminated recently from the AP syllabus, however, I feel that I must have a text that "does it all". It must include plenty of practice, without overkill, in many of the basic, traditional calculus topics, while simultaneously incorporating the contemporary approaches as well.
