Usually, it is very tough to imagine the difference in sensor sizes just by researching a spec sheet. The image underneath should provide you a much better sense of the sensor dimensions in the E-330 and K10D.

As you can see, each of these cameras feature different megapixels and different sensor sizes. The E-330 with its smaller sensor is going to make getting shallow depth of field harder and the Pentax K10D will render more detail with its extra 3MP. Greater resolution can also help you crop photos way more aggressively. The more aged E-330 will be behind when it comes to sensor tech.
