Well, I must admit that IntelliTrace looks nice, but let's not forget that it's very new and that the book was published in 1999. Also, what do you do if can't use a debugger for various reasons? I've debugged code using both approaches and while the debugger was nice, a good printf went a long way. On the other hand, I'm not good at debugging (other people's code), so I might not be credible :-)
