Stephen from AnandTech reviewed four ultra-compact digital cameras:

The Canon PowerShot SD400, Nikon Coolpix S1, Olympus IR-300, and Sony DSC-T33 are all recently-released 5 megapixel ultra-compacts that we decided to compare in this review. Each camera is different in terms of its overall responsiveness and image quality. It is our goal to present these differences to you in order to inform you in your quest for the right ultra-compact digicam.
