My guess is after reading the entire article that the author has a very specific workflow, one that is shaped by past experience with Linux. Since Apple is driven by a different mentality, he doesn't feel quite at home there. Power-User ways of doing things are different, and don't accomodate his way of working.
One thing I am slightly in the dark about is how much of chromatic's complaints deal with working in Aqua, how much deal with working with Darwin and BSD-based unix, and if it's possible to use Darwin without Aqua, using KDE or gnome instead.
This article is good for current Linux aficionados, those who have intimate knowledge of the Linux ways of doing things and a set habit. The problem is that this is actually a tiny minority of users, and not one Apple is likely to embrace.
I'm notgoing to say that chromatic is full of shit, as he's not. He's just going into detail about how he isn't as comfortable adapting to Mac OS X as he is in the Linux mould. I'm the other way, so used to Mac OS X and now Darwin's version of BSD that I don't feel all that comfortable in desktop Linux environments.
