In my opinion if you have cameras that do not match the way you see and work then you are not getting the work you are full capable of. Even though they might be inexpensive compared to others it's no bargain. Finding equipment that allows you to work at your fullest potential, no matter what the cost, is the real value. I am fortunate that my work pays for it all so I can buy and use exactly what I need. it just so happens to be Leica M at this point in time.
This is the absolute heart of what I'm saying about the value proposition.
This emotional (not saying that in a negative way, just as opposed to purely technical) side of the equation is as important as the solely technical side.
I understand that, I feel that way about a number of things, even certain straps, they just work for me.
On a solely technical level, they are not competitive, and then you add in the difference between the likes of CPN Canon servicing (I haven't used Nikon's so I can't comment) and Leica servicing, and there's several strikes against them in the technical column
This sentence is the one that jumps out at me though, towards the crux of what I've been trying to get across
"I can buy and use exactly what I need. it just so happens to be Leica M at this point in time"
You've bought the tools to do the job the way you like to do it, in your case, and currently the rangefinder experience has at least as much value as any of the purely technical considerations. I completely support that, even in the phrasing though it's the correct tool to do the right job at the right time.
That's the crux of what I'm saying, and with no ill will whatsoever, Leica lag behind on the technical side, and that makes them less of an option to many photographers.
I'd like to see them competing, on the technical side as well as the user experience, and seeing what work people can do with them then.
