In many cases, it is difficult to see the gap between sensor sizing simply by reading technical specs. The photograph here may offer you a far better sense of the sensor sizing in the E-PL3 and S3.

As you can tell, both cameras posses different megapixels and different sensor sizing. The E-PL3 using its bigger sensor will make shooting bokeh less difficult and the Panasonic S3 will offer greater detail having an extra 2 Megapixels. Higher resolution will also enable you to crop photographs somewhat more aggressively. The newer E-PL3 is going to have a benefit when it comes to sensor innovation.
