I got the Nikon Coolpix S5 series in Hong Kong when I wentthere about 2 years ago, and up until now, I am still using it. NO problems at all regarding malfunctions.
I just wish it had a better zoom range and better quality for pictures taken at night because they come out pixelized, but i know I can't have everything for such a small camera. The battery life is long (lithium ion) and it is very lightweight. It is very easy to bring around so honestly, I don't go home without it. I have snapped many pictures with it.
Another thing that I appreciate is being able to snap photos while I am on board a moving vehicle. The pictures are pretty sharp, as long as it is daytime. The nighttime shots are the only problem that I have encountered.
