Whenever I see high-ISO D700 shots, I want one.  Except that I don't 
want to carry it around  :-)

Just for laughs, I ran the your M8 ISO 2500 and 1250 pictures through 
Neat Image.  I did the kind of noise reduction I prefer--aggressive on 
chroma noise and sparing on luminance noise.  I usually don't shoot my 
M8 above ISO 640, so this was an interesting exercise for me.

Results here:

Compare the filtered M8 file at 2500 with the your Nikon ISO 3200 file.  
The Nikon is still better, but now things are a bit closer than they 
were before, probably within 1 stop.  If you view them both at 1:2 or 
1:3, which is how they will look when printed, then you can see that 
while the Nikon is still better, the Leica is still usable for 
reasonable print size. Things stay pretty gritty in the low tones unless 
I really smear the detail, which I don't want to do. 

Whatever Nikon is doing with on-chip noise reduction is pretty darned 
impressive. Neat Image can do some pretty amazing things with the noise 
in the midtones and highlights. But the M8 does seem to fall off the 
digital cliff at 2500, especially in the darkest tones.

At ISO 1250 (M8) vs. 1600 (D700), Neat Image on the M8 picture evens 
things out pretty well. I think the filtered M8 file is pretty  
comparable to the D700 file, even at 100%.

After what I've seen, I think I will be less reluctant to use ISO 1250 
when it's needed.

I'll leave the two filtered files up up for a few days.  Howard, if you 
want to grab the full-sized files and add them to your test folder, feel
