I'm not really up to speed on the P&S lines. I know the G series is a excellent camera and the fact they do not support RAW in the G7, that is really not of concern to you.
My advice is stay with Canon...I still have a S230 and it shoots great imgages at only 2.3 megapixels. They just released some new ones so take a look...you are in a price range that will buy you a pretty nice package. The SD800 or 900 has some nice features and is really compact.
Here is the Canon site for their P&S line.
