Digital BW, The Print

I'm not going to get in the middle of the pissing match part of this discussion, but I must admit that I too don't understand why one would want to mimic a particular film type.  Unless one were trying to match an existing silver print, I don't get it.  However, judging by the tweaks in the b&w converters (and even scanning software), there must be a market for it.
 
Digital gives me far more control over every part of the curve than was/is possible with film and chemistry.  Can someone tell me/us what the big attraction/use is for this 'feature'?

my method is to:

action:
create Curves adjustment layer (I)
create Channel Mixer layer (with a generic mix)
create final Curves adjustment layer (may be deleted if not used)

then I tweak the curve I RGB channel for overall contrast and Levels-
type adjust and then the individual channels to get differential 
channel mixing (the Channel Mixer is simply a linear combination and 
this gives you much more subtle and differential control).  The final 
Curve adjust is sometimes easier for overall adjustment than trying 
to do everything in the first one, especially if you did a lot of 
detailed RGB curve tweaks and just want to add an overal smooth s-
cuve for gamma control etc.  The final curve adjust also gives you a 
super easy way to "tone" your image... just tweak the individual 
channels.  I have tried the HSV method, but can visualize RGB much 
better.  Also, it is easier to actually look at your RGB channels and 
see what you are working with since that is a direct PS color working 
space and HSV technically is not (they give you the adjustments, but 
not the actual channels).
