After reading the article I think it is missing a couple of things. I agree with most of what you had to say, though. So without trying to offend anyone, I will to present a little bit different view.
Why do we take photos? Is it to post on blogs or websites? If so, any point and shoot will suffice and you spent way too much on Leica for the ability to do this. Is it to make a print? If so, then equipment matters. But even if your largest print is 8x10 there is an argument that equipment is less of a factor, but still important.
When I think of equipment, I am still stuck in an analog world where the only variable to equipment that mattered to me was the lens. Stick film in any camera, but give me the right lens. Digital has changed that because the sensor is now an important variable. Let me be clear that at this point I am not talking about the process of taking the photo. To some, the camera matters in that process. I get it. I am talking about the output, the print.
With the print in mind, what do I want that gives me the feeling that I am getting the best output? To me that is the Leica lens. Without a doubt, when I see the print, I am amazed every single time. There is a vision that I just don't get with any other brand. Leica is without peer. I have used them all. Canon L, Nikon's best, Olympus, Sony and Zeiss. I have not used medium format.
So Leica lenses are what I choose to use. The next question in the digital world is what sensor best gives the output that I am looking for? I want to use the Leica lens on the camera that meets my needs. If any camera that took a Leica lens, with or without adapter, worked for me then I would have a lot to choose from. But for my needs, the Leica M9 is what I prefer. I think Leica has done a great job of matching lens and sensor. If I could get what I prefer from a different camera, I would use it. I am not tied to rangefinder or any other process. I am tied to the output, the print. Leica gives me what I am looking for. I am done experimenting. Leica is it.
I hope this makes sense.
Regarding the marketing of the digital camera. Don't be fooled. Leica gets it. They are in a cycle of improvements of the digital camera and hope we upgrade each time they announce a new one. They are just not on the same pace as the other camera makers.
