This whole discussion, I have to say, is a little unbelievable.
People have been pining for ages about getting a full-frame sensor, and now that Leica delivers on it (despite their many statements about the immense technical difficulties this presented), people find something else to whine about.
Leica has accomplished a huge feat by actually producing a full-frame digital M camera with currently existing technologies. For years we heard it couldn't be done, but a team of dedicated workers has made it happen. I can't imagine how much time and expenses have been poured into the R&D of this project.
...and this is how we thank them?
To those who simply suggest that they put a CMOS sensor in the camera instead - CMOS sensors are known for the larger amount of physical space required for their housing. Can you imagine the reaction if Leica released the M9 with a larger body styling? I hear outrage. Not to mention that the "magic" of most CMOS sensor-based cameras out there these days relies more on the power of the processor to clean things up (just look at the Sony A900...).
I personally think the image quality of the M9 is spectacular. Look at this sample image at 1600:

Yes, it's noisy. But look at the detail! Even in the extreme corners, we see tack-sharp detail. Even though it's noisy, the noise has a very tight arrangement, and very little image quality overall is lost due to it. This is no small feat. With firmware upgrades, I expect Leica will clean up the noise issues.
All I'm saying is, let's stop the whining. Leica is a brand that needs support, not nit-picking and whining. They've done the unthinkable (and released it at a VERY reasonable price point, to boot!), and they deserve our thanks and respect.
And to those who are complaining about having to shoot at a lower ISO and a 15th of a second... I thought all Leica shooters were comfortable with much more absurd shutter speeds than that!
