Impressed (X20) :-)
Just got my X20 yesterday. I don't have a gallery of images yet, but I did do a quick set of ISO test photos. I have to say, I'm very happy with the performance for a company camera. The test photos are here: http://www.openbloom.com/Other/Fuji-X20-Test-Photos/n-cPFCQ/
Some other shots I took outside yesterday at low ISO were very sharp, detailed and very clean. Better than any point and shoot I've used with this type of a small sensor (or smaller).
