I asked for a Cannon D10 for Christmas and received a Pentax Optio W90. I don't know much about this camera. Have any of you used this camera? What do you think of it? Would I be better off returning it and getting the D10. I have been using an Olympus 1050 sw. I am really hoping to find a better option. So what do you think? Is the Optio W90 an alright point and shoot to haul around while fishing?
