Some very valid points in this thread.
I do agree that to get the 'digital rangefinder experience', yes the R-D1, M8, M9 and M-M and future M10 are the only ticket.
The Fuji cannot replace that experience completely, but for some of us who have experienced this "roulette" or aforementioned digital mechanical rangefinders, I think the Fuji does a good job of 'faking the funk' as it will that a mechanical RF offers. I say this, in the sense of having aperture control at the ring of the lens, shutter speed dial on top, and an Optical viewfinder. No rangefinder patch and mechanical framelines that move about.
It's just in my experience, the costly nature of repair for the aging digital rangefinders is too rich for my blood (right now); as is the dedication to spend that much up front for it anyways. I understand the "Pay to Play" aspect of owning those cameras. Maybe in the future when the M9 is within the few thousand, range it may become viable again, as an image producing machine to take out and have fun. I tried using my M8 for work photography and it did work, I racked up 8k actuations in a matter of a few months before the sensor decided to have a dead pixel and a $250-300 dollar remapping.
If you love it that much and wish to pay, then by all means there is no replacement. (I thought this way for a long time too, Noise performance, PAH, ~640 ISO hand-hold that shot) For some of us, the film M's are good 'enough' for that experience.
Sidenote, it's kinda neat being able to do 'Macro' with a OVF camera ! Like JSrockit mentioned about some of the advantages.
I'd get another M8 for fun, but as a main digital, probably not.
