I would be very cautious about upgrading to the S2. The noise problem is bad. Both Luc and Greg who also have an S2 will agree, unless you have perfect light, your going to get a very noisy image. I have to run most of my posts through NeatImage before I can even think about publishing here. Apart from that, I suppose its a good camera, though it does have some other idiosyncrasies. The lens cap is a very loose fit and is always falling off and most shots need to be adjust back -1 stop to cut out OE highlights. Most of my stuff is shot at ISO 100 or 200, sometimes 50 for landscapes and time exposures of waterfalls. It also does ISO 400, but I found that too noisy even in perfect light. It also has a lot of buttons and adjustment options. Sometimes you spend so long deciding which options to choose the oportunity of the shot has passed you by. Having said all that, I do like it, especially the supermacro option and the 12X zoom.
There are a number of other brands that have 12X zoom and I would does some serious research before handing over your hard-earned cash.
