I can tell the difference, if it's not done properly, and it isn't 
entirely trivial to do it properly.  For starters, you need a decent 
soundcard ... I've tried the stereo mini-in jack on this laptop and also 
on a couple of other older motherboards / soundblasters and the quality 
is _nowhere_ near the quality I get out of the VXpocket v2 with balanced 
inputs, and even that's probably at the lower end of the "prosumer" 
range.  Non-sound people I know can immediately tell the difference too. 
  I've heard enough badly ripped vinyl recordings that I don't really 
trust the general populace to make analog-to-digital encodings of any 
work.  Admittedly there are more complex factors involved with vinyl 
than with CD's, but if it's any indication ...

I would like to agree though, and also find copy protection of any sort 
to be ridiculous, in that "if I can read it, I can copy it". It's just 
that in practice there can be so many hoops to jump through that you 
start asking, "why do I even want this in the first place?"

Cheers,
Chris
