Sometimes, it's hard to envision the gap in sensor dimensions only by going through technical specs. The image below should give you a clearer sense of the sensor sizing in the GX1 and S1.

As you can tell, the two cameras provide different resolutions and different sensor dimensions. The GX1 featuring a bigger sensor will make getting bokeh easier and the Panasonic GX1 will provide more detail as a result of its extra 2 Megapixels. Higher resolution can also make it easier to crop shots more aggressively. The fresher GX1 will have an advantage in sensor technology.
