I think you might have taken his comment the wrong way.

I read as tho the author meant that the average computer user can't necessarily appreciate the elegance of a nice GUI interacting well with a UNIX-based operating system that provides rock-solid stability, speed, and efficiency.

The average WindowsXP user can't appreciate the complext inner workings of it as well (all Windows jokes aside.. Win2K & XP >are< stable and it does get the job done...

Basically, I think he just meant that the average user doesn't understand enough about computers to really appreciate what's going on underneath everything. The same way I can't really appreciate what a remarkable device an automobile is because I'm not a mechanic.

In short, ... chill. :)
