Generally, it can be hard to visualize the difference in sensor sizing only by seeing a spec sheet. The graphic underneath will help provide you a greater sense of the sensor sizing in the K-x and RS1500.

As you can see, both of these cameras enjoy different megapixel count and different sensor sizing. The K-x using its bigger sensor is going to make achieving shallower DOF less difficult and the Pentax RS1500 will produce extra detail using its extra 2MP. Higher resolution will allow you to crop photographs far more aggressively. The older K-x will be disadvantaged in sensor innovation.
