Thanks for the link The benefit of cameras like the G10 (and to some degree my G9) are that they produce quality images at a reasonably low costs (under $500), shoot in RAW, give you most of the shooting options and modes as do dslr's and though replace the need for macro and tele lenses, still allow for the addition of filters and a couple of additional lenses if desired. The primary advantage to me is the size when traveling, especially when you're not wanting to make it too obvious to the rest of the world you're a tourist. It fitd on my belt like a cellphone, or in my pocket. I keep it in my car much of the time, so I won't miss a shot I come across.
Like the reviewer, I'm not suggesting it's as good as a dslr for many applications, but it's not that far away. I certainly recommend it to anyone looking for an advanced point&shoot, whether it be their only camera, or one to keep with you as a secondary camera.
