PopPhoto published a review of the Sigma DP1, this new camera is the first compact digital camera that features a dSLR-sized image sensor:
Most compacts use smaller CCD or CMOS sensors (usually 7-9.5mm diagonally) whose pixels are just 2-3 microns wide, and use a striped or Bayer-pattern RGB filter array to help create a color image from black-and-white-sensitive pixels. At 24.9mm diagonally, the DP1's Foveon X3 Direct Image sensor measures far larger than most compact camera sensors. It also boasts 7.8-micron pixels (typical of 8-10MP DSLRs). Cameras with larger pixels tend to be more sensitive to light and have better noise performance at higher ISOs.
Check it out over here. This 14.1 megapixel digicam costs $799 but according to the site the image quality is unmatched in a compact camera. The DP1 has low distortion an performs well in low light conditions and at ISO 400 and 800 settings.
