More often than not, it is very difficult to imagine the gap in sensor dimensions only by going through a spec sheet. The image below will help give you a more clear sense of the sensor sizes in the 1 S1 and E-PM1.

As you can see, each of the cameras offer different megapixel count and different sensor dimensions. The 1 S1 because of its smaller sensor is going to make achieving bokeh more difficult and the Olympus E-PM1 will produce greater detail as a result of its extra 2 Megapixels. Greater resolution will also make it easier to crop pics a little more aggressively. The more modern 1 S1 should have a benefit with regard to sensor technology.
