Take into account, the weight of an Interchangeable Lens Camera will differ based on the lens you have attached at that moment. The following is the front view physical size comparison of the E-PL1s vs the ZS25.

Looking at dimensions and weight, the portability grade of the E-PL1s and ZS25 is 86 and 93 respectively.

Quite often, it is tough to imagine the difference between sensor sizes purely by looking at specifications. The pic below might give you a greater sense of the sensor measurements in the E-PL1s and ZS25.

Plainly, each of the cameras enjoy different megapixel count and different sensor sizes. The E-PL1s having a bigger sensor is going to make shooting shallower DOF less difficult and the Panasonic ZS25 will give you more detail because of its extra 4 Megapixels. Higher resolution can also allow you to crop pictures far more aggressively. The more aged E-PL1s is going to be disadvantaged in sensor innovation.
