sigma dp2. fixed len for compact camera?

Tweet

I was recently looking into to get a new compact one and cross over this one. The sample photos are very sharp and has a high contrast. I had seen both positive and negative review on internet. The fixed len is something that I never anticipate in a compact camera(kind of the killer, but maybe that why make it sharp). The full scale sensor CCD really makes the color rich. I was thing to take a try at B&H. but wondering if any one in this forum has any experience with this. Any comment is appreciate!! www.sigmaidp.com/DP2/technology.html
