No offense taken, but since the title of the thread is "Single Hammer Theory", and I'm the one who started the thread, I think my writing about the metaphor with the single hammer is kind of the point of the thread.
Okay, I'll bite. Comparing the new Leica M to the Leica M9. The analogy is the same. The Leica M9 was a purpose built rangefinder camera that did not try to be a DSLR, did not try to use any glass save the fine Leica M glass, did not try to shoot video, did not try to emulate a P&S with it's LCD screen used for focusing and framing, and was built to do one thing, take great pictures on a superior digital chip (the CCD, that few other cameras were using) with an optical rangefinder viewfinder. Plain and simple. It wasn't an attempt to build a "do it all" camera like Sony and Fuji were doing. And I respected that.
The new Leica M appears to be an attempt to compete against Sony and Fuji with DSLR capabilities, Optical viewfinders, Focus Peeking, Video, GPS, P&S style framing and focusing, etc.
That's a "do it all" camera in my book, compared to the purpose built M9.
Best,
