Typically, it is very difficult to visualize the difference in sensor sizes merely by seeing technical specs. The pic underneath should give you a stronger sense of the sensor sizes in the PX and DP1s.

As you can tell, each of these cameras have different megapixels and different sensor sizes. The PX with its smaller sensor is going to make getting shallow depth of field more difficult and the Ricoh PX will provide greater detail with its extra 11MP. Higher resolution will also allow you to crop pictures a bit more aggressively. The fresher PX should have an advantage in sensor technology.
