The RX100 is probably the most capable compact camera on the market today, combining the image quality benefits of a mid-sized sensor with the proportions of a conventional compact. Extensive, though not flawless, manual controls make the RX100 a great second camera for DSLR shooters.
1" CMOS Sensor /20-100mm/F1.8/FullHP recording/StereoMic/USB Charging/10framePerSecond etc makes it pricey. It fits in your pocket and you get a very good image (even at low light).
CMOS sensors are normally costlier than CCDs.
There is a image comparison on 12th
page of review there. Check with basic DSLRs and this. You will be surprised :)
