I shoot a D300 and can feel your DSLR pain.
Once you accept that the G10 isn't a DSLR and it never will be, you'll enjoy your camera much more. It is a point and shoot that has a lot of features but all in all - it is still a point and shoot compared to your DSLR.
I was a little upset about the performance as well when I first got mine but after learning it's quirks, I've decided to keep it. Once you learn it's weak/strong points you'll be happy you got it. I suspect you might want to go to MY COLORS and bump up your contrast and saturation just a bit.
If you want the most detail - shoot low ISO, RAW+JPEG and enjoy.
I hope that helps...
