Having just picked up a Leica M8, I can see the attraction for using the M for landscape work. I've been shooting with my M while hiking, and it works very well, you hardly notice it around your neck. Framing is an issue, especially if you are used to exact compositions in the viewfinder. With the M, the framelines are ballpark, with the lens I have I get image area that is outside the frameline, so a bit of cropping brings it back to my original composition. The Lenses are small, and superb (I'm shooting with Zeiss ZM lenses currently); the sharpness and contrast of the images from the camera, without sharpening, is astounding. I'd never shot with a camera that didn't have a AA filter, the difference is remarkable. So, in 3-5 years, when the M10 comes out, and the M9 is more affordable (for a Leica), I'll be upgrading.
