Well, I know this isn't really what you have in mind, but the Leica M cameras are practically pocketable.

Actually, Leica does make a point and shoot that DOES have amazing glass. I bought one about five years ago before beginning a job that took me to Europe, and I was very happy. It has kind of a crude manuel focus, and manual selection of both aperture and shutter speed if you want. And I was very impressed with the photographs I was able to make with it.
