No - it's there's no swapping because there is no need for swapping on 
my system.  If I were to run a lot more apps that needed a lot more 
memory concurrently that would change (but then I'd bump up the memory 
as well probably outpacing the need for more memory at a given time.

 From whatever else may be going on.  True to say that as I have a quad 
core HT i7 that the computer has oodles of idle time most of the time, 
but on the other hand why write to disk when there is no reason to do so?

Well enough to know that on a systems with large amounts of RAM, swap 
and compression are not needed for many users.

Hmm.  When I turn them off then obviously they are not used at all and 
there is no ill effect on my computer or operations with the computer 
not being re-booted for weeks.

As memory gets cheaper and larger the need for swap and compression 
dwindles.  Not for all users and operations of course, but certainly for 
me and certainly for a lot of users.
