Typically, it is very hard to visualize the gap in sensor sizing merely by viewing a spec sheet. The graphic here will help give you a much better sense of the sensor sizing in the E-PM1 and 7040.

As you can see, both of those cameras posses different resolutions and different sensor sizing. The E-PM1 using its larger sensor is going to make achieving shallow DOF less difficult and the Olympus 7040 will result in more detail because of its extra 2 Megapixels. Greater resolution can also let you crop pics somewhat more aggressively. The newer E-PM1 should have an edge when it comes to sensor technology.
