Normally, its hard to picture the difference between sensor sizes only by looking at specifications. The picture here may give you a much better sense of the sensor sizing in the E-330 and Q-S1.

Plainly, both cameras come with different resolutions and different sensor sizes. The E-330 having a bigger sensor is going to make achieving shallow depth of field less difficult and the Pentax Q-S1 will give you more detail because of its extra 5MP. Higher resolution can also allow you to crop pictures a good deal more aggressively. The more aged E-330 is going to be disadvantaged with regard to sensor innovation.
