I have the Leica X1. It's one of the best cameras, let alone compacts, that I've ever owned. The quality is mind blowingly good and you will find it matches or probably betters an SLR of the same resolution and quite possibly more. It beats my Canon 5D for colour, detail micro contrast. The large chip and outstanding lens make for some incredible pictures. There's next no barrel distortion on the lens, unlike the Fuji, which is so important for a camera like this with taking decent portraits. 100% crops are eye poppingly good. Really, the whole experience in such a small, simple and effortless design is really liberating.
It does have it quirks, the focus is a bit on the slow side (not much slower than the Fuji x100 though) but personally I found once you know what they are and you are used to them you find your way around them. It has a manual focus function on it that I love and use a lot.
To give you an idea I spent months researching and I found nothing that compared to the Leica X1. I was so taken by the quality of the camera that I've now bought an M9 kit and done away with the Canons.
The pics speak for themselves - Have a look at the output from this guy:
