Sometimes, it's hard to see the contrast between sensor measurements only by reading through technical specs. The visual below might give you a greater sense of the sensor sizes in the S100 and A900.

As you can tell, each of the cameras have different resolutions and different sensor measurements. The S100 with its bigger sensor will make achieving shallow depth of field less difficult and the Nikon A900 will give you greater detail using its extra 8 Megapixels. Higher resolution can also help you crop shots a bit more aggressively. The older S100 is going to be disadvantaged in sensor tech.
