Always remember, the weight of an Interchangeable Lens Camera will change depending on the lens you are using at that moment. Below is a front view dimensions comparison of the E-330 vs the H90.

Using dimensions and weight, the portability score of the E-330 and H90 is 65 and 93 respectively.

Normally, it is tough to visualize the difference in sensor sizing simply by looking through technical specs. The graphic here should offer you a better sense of the sensor dimensions in the E-330 and H90.

As you can tell, each of these cameras provide different megapixels and different sensor sizing. The E-330 having a larger sensor is going to make shooting shallower depth of field less difficult and the Pentax H90 will render more detail using its extra 5 Megapixels. Greater resolution will also enable you to crop pics more aggressively. The older E-330 will be disadvantaged when it comes to sensor innovation.
