Often, it is very difficult to visualise the difference between sensor measurements only by reading through a spec sheet. The visual here might give you a more clear sense of the sensor sizes in the E-PL3 and SZ7.

As you can see, each of the cameras have different megapixel count and different sensor measurements. The E-PL3 having a larger sensor will make achieving shallow DOF less difficult and the Panasonic SZ7 will give you extra detail having an extra 2MP. Greater resolution will also let you crop photos a bit more aggressively.
