We call them 'dentist photographers' in German photo forums. These guys get always the most expensive stuff and all they do is taking test pictures of screws and newspapers to determine if the optics are flawless. Then they put their expensive Leica away and go golfing.
It works out great for everyone else though. If you look at used Leica M9s on the market (as I'm doing these days...) a great many of them have only collected ~500 shutter clicks in the years they've been "in service".
Whenever I see a great camera sitting around unused it makes me ache :(
Have they fixed the chromatic aberration issues with it yet? I couldn't imagine paying $6000+ for a body anyway, especially one with such fringing issues. If you haven't considered it, you might want to check out the X100S. Check out Zack Arias' review. He specifically discusses the camera in the context of Leica: http://zackarias.com/for-photographers/gear-gadgets/fuji-x10...
I'm not aware of any unusual CA issues with the M9. Are you talking about the UV issues with the M8? Those were fixed for the M9, but unfortunately never fully fixed with the M8's...
CA is largely an artifact of the lens, not the sensor, no?
In any case, you can pick up a barely used (makes me weep with joy and sadness at the same time) M9 for about $3500 these days... It's the only reason why I'm even considering it. $7K for a body is insanity.
I did manage to get to play with a preproduction X100S by a stroke of luck. I like it, but it's not really the shooting workflow I'm looking for. I have the OM-D for that.
