Typically, it can be tough to visualize the difference between sensor measurements only by going over a spec sheet. The photograph here may offer you a much better sense of the sensor sizing in the DP1 and T90.

Clearly, both of the cameras posses different resolutions and different sensor measurements. The DP1 featuring a bigger sensor is going to make getting shallower DOF easier and the Sony T90 will offer you more detail due to its extra 7MP. Higher resolution can also enable you to crop pictures somewhat more aggressively. The older DP1 is going to be behind with regard to sensor innovation.
