What Curval said.
Canon makes some more expensive and less expensive PowerShot SD Elph models, any of them are great, fit into a pants pocket easily and are easy to use. To download pictures you just plug the provided wire into the camera and USB port; it’s just as easy to use as a dock, takes up less room and costs less. A downloading alternative is a cheap card reader. Seriously, docks are a marketing ploy that makes an already incredibly simple task just as simple. I’ve used Sony, Olympus, Vivitar, Oregon Scientific, Canon and Nikon digital cameras. The first four take pictures, but are too pricey for their quality. Canon and Nikon take fantastic pictures, are very reliable and easy to use. Get him an Elph.
