In many cases, it can be hard to see the gap in sensor sizes simply by going through specifications. The pic below will provide you a clearer sense of the sensor dimensions in the E-M10 and RS1500.

To sum up, the two cameras come with different megapixels and different sensor sizes. The E-M10 using its bigger sensor will make shooting shallower depth of field easier and the Olympus E-M10 will show greater detail having an extra 2 Megapixels. Higher resolution will let you crop shots a good deal more aggressively. The more recent E-M10 is going to have a benefit with regard to sensor tech.
