I've got the Pentax Optio WP, same deal, 5Megapixel, stainless housing, waterproof to a couple of metres, takes a good shot. Only thing is the video isn't that great if you're zoomed in, but hey everything else is great

Hey Zed,
Once you download your pictures to your computer, open them up in an image editing program, crop them so you get only the bits you want, and then resize them to be something more like 800 x 600. This reduces the file size so you can email them or stick them on the web.
