Congrats on your purchase! I've had mine for a month now and I love it.
With no AA filter the IQ is superb! It's right up there with my DA15 which is the closest prime that I have to compare it to. The real advantage of the camera obviouslly is it's size.
It goes with me where I normally I couldn't be bothered to take my K-5.
People also tend to think it's more of a toy camera of even a phone which is fine by me.
BTW, I also shoot RAW also and have never even taken a .jpeg shot with it. I really need to try out the .jpegs...
