I would forgo the RAW, unless you are really interested in post camera image enhancement, I have the RAW hack on my 570 with similar limitations. I don't shoot as many pics as you but I have stopped using the hack except if I really want something to play with. Others will disagree, I can live without RAW for fun photography. The 570 and 590 do a good job with their in camera firmware. The one place I have a use for the RAW, shooting my fisheye and ultra wide angle lenses it is easy to get blown out highlights (sun, reflections in the corner etc) and the RAW seems to let me get more dynamic range it seems, however, if the data is not there, completely blown out, it does no good anyways.
The dSLR shooters are coming at this from a different perspective than those of us who shoot for fun with P&S cameras. Several of them could no tell the difference between a Nikon D3 pic in RAW vs the P&S jpeg, when you are web displaying or making 4X6 prints, well,it is not the same as a cover shot or a serious amateur trying to push the limits of his equipment and skills.
