I'm very pleased to be using this text in the college course I teach for math majors.  It's exceptionally clear and contains exactly the most important topics for new mathematicians to learn.  I have a few small disagreements with Houston (for example, he says 0 isn't a natural number), but these are far outweighed by the quality of his explanations and the excellent homework exercises he provides.  Any student who understands the material in this text is very, very well prepared for study of upper-division pure mathematics.<br><br>My one real complaint is that this is the worst-bound book I've ever owned; it started falling apart the very first time I used it.  My students this quarter have been working through this text for a week now, and almost every one of their copies already has pages falling out of it.  Maybe the hardbound version doesn't have this problem?  I hope Cambridge Univ. Press learns about modern binding practices soon...<br><br>Besides that, though, this is an excellent text - head and shoulders above the similar texts I've considered for adoption in my courses.
