Sometimes, it's difficult to imagine the gap between sensor measurements merely by reading through specifications. The graphic underneath might give you a far better sense of the sensor sizes in the K100D and H90.

To sum up, the 2 cameras enjoy different resolutions and different sensor measurements. The K100D using its bigger sensor is going to make getting shallower depth of field easier and the Pentax H90 will give you extra detail using its extra 6MP. Higher resolution will help you crop shots far more aggressively. The older K100D is going to be behind in sensor innovation.
