Sometimes, it is very difficult to visualize the difference between sensor measurements simply by going over a spec sheet. The visual below may give you a greater sense of the sensor measurements in the E90 and DP2.

As you can see, both of those cameras posses different resolutions and different sensor measurements. The E90 featuring a tinier sensor is going to make shooting shallower depth of field more difficult and the Pentax E90 will deliver greater detail as a result of its extra 5MP. Greater resolution can also let you crop images somewhat more aggressively.
