In fact back-ticks work perfectly well, but I tend to use the other form 
as back-ticks cannot be nested, while $() can. Also, back-ticks have 
some graphical proximity with apostrophes, that is a bit disturbing for 
a native French writer ;)
It's just as preferring curly braces around shell variables, it's a kind 
of coding style.

As for the discussion about how variables (and some other things) are 
handled in particular ways on unix/linux, I may agree to some extent, 
but am sure the past unix-wars have taught us well how to stay out of 
trouble :p
