I picked up a Digilux 1 as soon as it became available and use it primarily as a "carry everywhere" camera, much the same as I used to always take a film point-and-shoot with me. My expectations never were that I'd have a camera that would rival the M6 for image quality, so I have been disappointed the way many have. On the other hand, it has produced saleable images on many occasions. As with ALL digital point-and-shoot cameras made today, there is significant noise at ISO settings above 100, but the only solution to that is to put a much more expensive sensor in the camera and raise the price considerably.
So, I've been very happy with the Digilux 1. I find it easy to operate, comfortable to carry and capable of producing high quality images.
