Often, it can be tough to imagine the gap in sensor sizing merely by looking through technical specs. The photograph below will help offer you a more clear sense of the sensor sizes in the G900 and DP1.

As you have seen, both of these cameras provide different resolutions and different sensor sizing. The G900 with its smaller sensor is going to make shooting shallower DOF tougher and the Ricoh G900 will provide you with extra detail using its extra 15 Megapixels. Greater resolution will allow you to crop photos more aggressively. The fresher G900 should have an advantage with regard to sensor tech.
