Oftentimes, it's tough to imagine the difference in sensor sizing only by going through a spec sheet. The visual below will offer you a more clear sense of the sensor sizing in the GF1 and WG-1 GPS.

Clearly, each of the cameras posses different megapixels and different sensor sizing. The GF1 having a bigger sensor is going to make shooting bokeh simpler and the Pentax WG-1 GPS will provide more detail with its extra 2 Megapixels. Higher resolution will help you crop photographs somewhat more aggressively. The older GF1 will be behind when it comes to sensor tech.
