Generally, it is tough to picture the difference in sensor sizes just by seeing a spec sheet. The picture below will help offer you a more clear sense of the sensor dimensions in the E-510 and WG-1 GPS.

Clearly, both the cameras posses different megapixel count and different sensor sizes. The E-510 having a larger sensor is going to make getting shallower depth of field simpler and the Pentax WG-1 GPS will provide greater detail having an extra 4MP. Greater resolution can also let you crop images somewhat more aggressively. The more aged E-510 will be disadvantaged in sensor technology.
