Quite often, it is very tough to picture the difference between sensor measurements just by going over a spec sheet. The graphic below will give you a more clear sense of the sensor sizes in the E-PL3 and S1.

As you can see, both the cameras provide different megapixel count and different sensor measurements. The E-PL3 featuring a larger sensor is going to make achieving shallower DOF less difficult and the Pentax S1 will offer more detail due to its extra 2 Megapixels. Greater resolution will also make it easier to crop pics more aggressively. The younger E-PL3 should have an advantage when it comes to sensor technology.
