[Digital BW] Re: Dedicated Black and White System Overview

2007-03-07 by Steve

I think I understood some of that Paul....

The thing is, I don't want to know as much as you obviously know 
about all of this.
I realize that attitude might get my lynched on a technical board 
like this...but it's true.
I want to be able to drop in carts, do some adjustments in software, 
and have a better than fair chance of getting results that please me.

To drive a nail, I need to know how to swing a hammer.  I don't need 
a background in physics.  
Because I trust in the power of the marketplace.  I'm pretty sure 
that there is now, or will be in the future, a perfectly useable 
selection of hammers out there from which I can choose one or two 
that fit my needs.

I'm grateful there are folks out there thinking of these things in 
the terms you describe...I'm just never going to be one of them.
