This looks really interesting. I've been looking at a compact for a few years, and have yet to pull the trigger. The s100 is still experiencing QC problems from what I can tell (lens decentering, lens errors..etc). The XZ1 looks best on paper, but as primarly a jpeg shooter, I am dissapointed with the lack of noise reduction control in camera. I also really don't want to have to deal with a lens cap. The LX5 is probably going to be replaced soon. I guess I'd rather do without than have money spent into something I don't like.
So, I've pretty much held out. This looks awesome on paper too, but we won't know until its tested.
