It is funny how this discussion comes up over and over again.
Everybody should use what they like not what others like.
Yes, the funny side is that every Leica talk ends up with some irrational arguments (great photographers used it bla-bla, best craftmanship bla-bla, etc...) from the picture standpoint. It is like Leica owners want to be convinced they did a good choice and need for that a kind of social recongnition from the photo community. Sorry but to me, photography is much bigger than that.
