*ist-Ds Vs. K10D image quality?

[Mark Erickson]

All, 

After nearly 2 years, I'm still happy with my *ist-Ds (except for the name, 
of course).  I'm getting results I like (even without Shake Reduction) and 
I'm really comfortable with it as a tool.  I shoot only raw and have a 
post-processing workflow that I find fast and easy. 

Soooooo, for all of you *ist-D[x] users out there who have upgraded to 
K10D's, can you comment on image quality improvements (or lack thereof) 
between the two camera generations?  Does 10 really beat 6 in the real 
world?  Your thoughts? 

Thanks, 

Mark
