Anyone ever use a DSC-U50? Can you post some images from one please? I like the style of the camera but I am concerned about the 2 Megapixel limit. I am not concerned about zoom....I just want the smallest camera I can find to keep on a keychain or the like so it is available at any moment to take a photo. ....just a side comment here...I am not a fan of the phones with a camera in them...so that is not an option for me.
