Just picked up mine yesterday. I had no regrets with the G7 so I don't see any reason to regret the G9 unless the RAW sucks 
I've just installed the Lightroom 1.3 upgrade and the RAW files look good so far re. white bal, which was my major gripe with G7 hacked RAW workflow.
I'm impressed with the way the G9 handles RAW write speed and you can almost take a picture straight after unlike the G7 with the CHDK!
I've never felt totally comfortable holding the G7 as it doesn't have much of a protruding grip so I have ordered the Custom Grip and thumb rest to give it a better feel. The G9 feels a little better than the G7 but only marginally.
Grip can be seen here
