I've handled the RX100. It's like a bar of soap. I agree the pics are allright and it rocks at high iso. I'm ok with the Fuji, it's an "old school" (like me) camera of the right size (for me) with proper dials, sensible features and a simple menu system. Plus superior color rendering. If I need technically better results I use my X100 or Nikon D700.
For me the handing of the X series cameras is an important component of using it. Every other compact camera i've handled (except a Leica M, if you count that as "compact") felt like a piece of plastic that takes pictures. I hate electronic motorised zooms, and i don't like holding a camera at arms-length when taking pictures. My X10 feels like a proper camera: The manual zoom adds great tactility, and it has a half decent VF. The X20 fixes the only real failing of the X10 in my opinion - electronic display in the VF. For me, the RX100 might well take better pictures, but it's not as satisfying to use.
