I've had this camera for four months now and I'm very satisfied. I used to have a Sony W5 which was a great camera, fast (point and shoot) and ran on AA batteries. I then bought a Nikon L5 and was very disappointed in its ability to focus quickly in low light and very slow shot-to-shot times. I used the 850's predecessor, the 700, and was impressed with the speed of most functions compared to the Sony and Nikon. I was wary of proprietary batteries, so I bought an extra battery when I bought the camera and haven't needed it yet when shooting. It's a good idea to have an extra power supply anyway. If you start with a freshly charged battery, you probably won't need it. The picture quality is excellent, there are many modes available, but in most cases the automatic mode works well. I love being able to record videos with such a compact camera. I have a miniDV camcorder, but I almost never carry it because of the extra weight. With this camera I can handle most of the situations where I want to capture my two and a half year old son. Manual modes are limited compared to the SLR, but this camera can move discreetly anytime, anywhere. If you are looking for a portable digital camera then this is not for you. If you are looking for a camera that you always have with you to capture spontaneous moments, this is the camera for you. Image stabilization definitely helps, but don't expect every picture to be perfectly sharp.
