The G1 X's body design is quite similar to the G12's, though slightly bigger and heavier. While there's a lot to like in the camera's specs, especially the large sensor, the lens looks a bit disappointing; at f2.8 the aperture doesn't start out very wide, and it gets pretty narrow at a not-terribly-long focal length of f5.8. Plus, while that knurled ring around the lens looks like it'd be great for focusing or zooming, it's just there for show.
