I have been using Logic 10 years, and its fairly comfortable, but I did find it annoying for quite a while. I am not sure why. Perhaps it was the early manuals without indexes and various german words. i think there is some stuff that is just not polished or explained or perfected as much as it should be. at least now there are additional logic books too which were not around then. the thing that helped a lot was seeing people use it in action at demos too.
