Factoring in dimensions and weight, the portability score of the PX and DP2x is 95 and 86 respectively.

Sometimes, its tough to visualize the difference in sensor measurements merely by researching a spec sheet. The graphic below might give you a stronger sense of the sensor dimensions in the PX and DP2x.

As you can see, both cameras feature different megapixel count and different sensor measurements. The PX using its smaller sensor is going to make achieving shallower DOF trickier and the Ricoh PX will provide you with greater detail using its extra 11MP. Higher resolution will also make it easier to crop shots way more aggressively. The fresher PX provides an advantage when it comes to sensor technology.
