Richard - a prosumer point and shoot is almost an oxymoron in terms. A prosumer is a consumer that's almost at the level of a professional - i.e., it's the level of performance that falls between professional and hobbyist. A point and shoot is a camera that has auto-everything that allows you to literally point the camera in a certain direction, push the shutter button, and get decent photos. Typically, it has a fixed lens with a built in optical zoom. A step above this would be a digital SLR with a single reflex lens design allowing a true WYSIWYG framing of shots and using interchangeable lens much like a standard film SLR. A prosumer point and shoot is a camera that does the point and shoot thing but also allows enough manual control that allows you to fine tune the picture to suit your needs. The Fuji Finepix I was talking about is a fine example of a prosumer point and shoot, as Wes has mentioned as well (it IS a little big, isn't it, Wes?).
