The A100 was announced 5 years later than the S3100 and that is quite a big gap as far as technology is concerned. Each of the cameras feature the same body design (Ultracompact).

Before delving right into a more detailed comparison, here is a quick overview of how the A100 grades vs the S3100 when considering portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Nikon Coolpix A100 and Nikon Coolpix S3100. The whole galleries are available at Nikon A100 Gallery and Nikon S3100 Gallery.

For those who are planning to lug around your camera frequently, you'll have to consider its weight and dimensions.

Typically, it is very hard to visualize the gap between sensor measurements simply by reviewing a spec sheet. The photograph below should provide you a greater sense of the sensor measurements in the A100 and S3100.

Clearly, both of those cameras come with the identical sensor size albeit different MP. You should count on the Nikon A100 to deliver more detail with its extra 6 Megapixels. Higher resolution will also enable you to crop pictures a good deal more aggressively. The more recent A100 should have a benefit when it comes to sensor technology.
