Often, its difficult to imagine the difference in sensor dimensions merely by researching technical specs. The image below may give you a far better sense of the sensor sizing in the K100D S and P80.

As you have seen, the two cameras provide different resolutions and different sensor dimensions. The K100D S due to its larger sensor is going to make getting shallow depth of field easier and the Pentax P80 will provide you with more detail as a result of its extra 6MP. Greater resolution can also allow you to crop images more aggressively. The more aged K100D S will be disadvantaged with regard to sensor tech.
