Query: Good ideas, but horrible context

I praise Ostebee and Zorn for making an attempt to make calculus easy and for everyone. But I just don't think that is true. Calculus is a sophisticated form of mathematics and sometimes it needs to be taught with vocabulary and methods within the mathematics community and outside of everyday life. When you combine this with the usual high number of mistakes present in a first-edition book, a great deal of the phrase "we'll discuss/define this soon", excessive use of the graphing calculator, and some pretty lame jokes, you get a product that's not really worthy of being used in a college-level course.
