I love my rangefinders, I love my Leicaflex, my Nikon FE, and my Hassy, but when it comes time to do most of my professional freelance work (which is often outdoors, at night, and can be in adverse weather)...my Canon 1D MKIV and a 1DS MK III will handle everything I can throw at them and then some, all without my having to worry about moisture or the occasional hard hit. Those bodies and three primes...24L, 35L, 50L...are pretty much my bread and butter. And while I love Leica...my local Canon Professional Services location is three blocks from my office and I never have to worry about being short a piece of gear because its off for some kind of maintenance. I've been sorely tempted to switch over to digital Ms for the higher IQ but Canon's professional support and the robustness of their gear is something that Leica simply can't match. Leica is a small company with different design priorities/philosophies, it just can't be helped.
The DSLRs aren't particularly "magic" to use, and their output isn't particularly "magic" to me either....ironically my favorite images taken with my Canon setup involves R-mount 50mm and 35mm Summicrons. Compared to manually-operated rangefinders my DSLRs don't even feel like I have to think at all use them (and I don't like that kind of user disconnect) but...they are durable, solid, reliable tools.
If cameras were like paintbrushes, 1-series DSLRs are autofeeding spray guns that will paint a whole house in like an hour. My DSLRs get the job done fast and with minimal fuss, in some respects they are so advanced they bore the **** out of me when I'm using them. My RF/traditional gear is more like a fine horsehair paintbrush. Skill is required to use them, and you have to do your own work but the results are so much more unique and "special".
