Plainly, both of those cameras enjoy different megapixels and different sensor dimensions. The A100 having a bigger sensor is going to make shooting shallow DOF simpler and the Sony W310 will show greater detail with its extra 2MP. Higher resolution will let you crop pictures far more aggressively. The more aged A100 will be disadvantaged in sensor innovation.
