In the class of ultra-compact cameras, every inch counts. Until Sony implements a new lens system on their slim cameras, they will suck. Sony has also jambed 7.1 million pixels into a 1/2.5″ CCD (in fairness, so did Canon) So, not only is the resolution going to be bad, but the light sensitivity of each pixel will also suck. If you want blurry pictures and only want shoot in bright daylight, pick up the Sony. Otherwise, consider getting anything ELSE.”]
