This one has got me going too. 5.4 oz, at that size, with all that imaging capability. I'll wait for the tests though, because 12 Mp. in a 1/1.6 sensor with clean hi-ISO is a little hard to believe. If it's at all decent, I'm buying.
Think of the sort of photos this looks to be good for: those grab shots where you don't have time to compose. I hope it's that fast. Consider that IQ will be equal to or better than the G-9, at 1/3 the weight. A good JPG is much better than no image, and I'll be very likely to have this featherweight in reach ALL the time. As for the quality difference between JPG and RAW, I promise that there are very few people who can truly discern that. If you set up the orig. image to get the least in-camera processing, and then batch convert directly from the card into TIF, DNG or PSP format, the difference is academic.
