I can understand his argument about tinkering and distractions, but personally for me it is all about apps. If Linux had the same polished apps like OS X has then I would probably use Ubuntu as my main OS.
Actually two of my favorite apps ever are on linux, Amarok and Digikam. However, in full disclosure I haven't used Mac seriously in a while. I am sure there would be things I would love on it but for the most part I am very happy with the apps available for linux, especially now KDE4 is becoming usable.
Funny, I use four "apps" more than any other software on my computer: Shell, Emacs, Firefox, Thunderbird. That's it. Sure, every now and then, I'll run some other program, say, Evince, Synaptic, Nautilus, or occasionally even The Gimp... but frankly compared to my usage of the other four, everything else is statistical noise.
The development tools I work with every day are either accessible from within Emacs or I run them from the Shell. In other words: I'm old school.
Anyway - my point is: the original post was how Mac OS provides less distractions, and your argument of having more apps available seems to claim the opposite.
