Query: Nice Book

If you are a Programmer not in College, this is a nice book. As I read it, I learned several new things but then when I took Operating Systems Programming, I realized that we went over everything in the book, more in depth, and then some. If you aren't a Computer Science Major and you want to really program on the Mac, buy this book. However, if you are going to College, save your money. Let your professor teach it to you.
