Don't forget, the weight of an ILC will change based on the lens you use at that time. Below is the front view physical size comparison of the TG-870 compared to the DP2s.

Considering size and weight, the portability grade of the TG-870 and DP2s is 91 and 86 respectively.

In many cases, it is difficult to imagine the contrast between sensor sizes merely by looking at specifications. The picture underneath might give you a far better sense of the sensor measurements in the TG-870 and DP2s.

To sum up, the 2 cameras offer different resolutions and different sensor sizes. The TG-870 because of its tinier sensor is going to make achieving shallow DOF more challenging and the Olympus TG-870 will give you extra detail as a result of its extra 11MP. Higher resolution will let you crop photographs a little more aggressively. The more recent TG-870 should have an edge when it comes to sensor tech.
