To audyssey or not to audyssey, that is the ...?

Hi,
Wondering what everyone's opinion is on using audyssey for sound improvement? I know there are two camps on this, one is to leave the speakers and sources alone and use outside corrections and there is the other that believes in electronic room corrections. I fall into the 1st category but I am being told otherwise by a local ht dealer and he says to wait till they get in some new equipment to prove that audyssey is the way to go.
Anyway looking for thoughts from both sides. I plan on having a 2ch system (Parasound JC2 + A21) and 3 ch (MCA 30? + Parasound hdp70 or Halo c3) plus vandy quatros for fronts and mb quarts for rear and von schweikert center. Look forward to hearing y'alls input.
