Digital BW, The Print

While most folks posting here likely use Photoshop, I'm curious to know 
if some use PSP X2? I'm downloading the demo but would like to hear 
from those with real experience at exploring just what it can do. For 
photo-only work, how does it compare to PS? I see it has some level of 
RAW support, curves, layers, and so on, but are these adequately 
developed for serious work? Any users out there?
