Imaging-resource published an extensive review of the 4 megapixel Coolpix 4600 digital camera from Nikon.

Super-tiny and compact, the Nikon Coolpix 4600 is easily among the smallest digital cameras currently on the market (as are its sister models the Coolpix 5600 and 7600). Not much larger than a credit card, the Coolpix 4600 is designed to fit nicely into shirt pockets and small purses, perfect for travelers. It's so tiny (weighing just 6.7 ounces or 189 grams with the battery and memory card loaded), I'd highly recommend keeping the included wrist strap securely around your wrist when shooting.
