The Sigma DP series is somewhat controversial. 
It claims to pack DSLR quality in a P&S body, which for all its marketing hyperbole is literally true as it contains a DSLR-sized sensor in a rather compact frame. Indeed, the sensor is a Foveon, which is a different animal from the typical Bayer sensors; some claim that it renders colors in a very tonally smooth way not unlike film. Its chief quirk is that it has very slow response times, it feels positively geriatric. Were one to use a typical SD card, it takes about 3-4 seconds to write a RAW image. Plus the camera locks up during this period. However, the prime 28mm equivalent lens is capable of producing extremely sharp images with minimal distortion and no lens flare, which is quite nice for something this wide. Upon turning the camera on, the lens barrel gives a strange mechanical sound as it extends--another slow performer. The camera is nicely designed, a mere black box in light aluminum with chrome lugs. It is best used with a separate viewfinder, and looks quite fetching with both hood and viewfinder attached. Some photos from the DP1 with minimal processing from RAW to jpeg:
