Usually, its hard to envision the contrast between sensor sizes just by reading through a spec sheet. The pic underneath might give you a far better sense of the sensor measurements in the SD15 and W730.

Clearly, both of these cameras feature different megapixel count and different sensor sizes. The SD15 because of its larger sensor will make getting shallow depth of field easier and the Sony W730 will resolve extra detail as a result of its extra 11 Megapixels. Greater resolution will allow you to crop images way more aggressively. The more aged SD15 is going to be disadvantaged in sensor innovation.
