I would argue that he does point out that OO is good for certain types of applications, specifically GUI applications. I do agree with you that the application paradigm is often overly touted as the epitome of good design, but that doesn't change the fact that the original design ideas behind Unix were good ones. On the other hand, I would also argue that modern Unix software (at least in the Linux world) rarely follows that paradigm. Most desktop applications in Linux follow precisely the same methodology (and inherit its flaws) as Windows applications. They are often big, bloated, and slow.
