You're absolutely right, Nick

, and thank you
The pipe organ I play at the church does not have one single nicked pipe whatsoever. This translates into a very natural sound along with all the characteristics of the air entering the pipe, which is never quite the same for each key suppression. There are lots of "mechanical" sounds ... it's a very chiffy organ ... and I love it for that quality.
In defense of the digitals though, they are improving every year ... still for some the only alternative due to space constrictions and/or budget concerns. I would rather see a "normal" digital installed in a church as opposed to a simple portable keyboard.
My main complaint on the demos for the digitals is their incessant use of extraordinarily long reverb times. Relatively few churches (at least here in the US) have reverberant buildings - many, like mine, are completely devoid of any acoustics ... the sound stops before I lift my hands of the keyboard in my church
