Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Samsung NX100 and Nikon S31 side-by-side from the front, back and top in their relative dimensions. Samsung NX100 has external dimensions of 120 x 71 x 35 mm (4.72 x 2.8 x 1.38″) and weighs 282 g (0.62 lb / 9.95 oz) (including batteries). Nikon S31 has external dimensions of 105 x 65 x 42 mm (4.13 x 2.56 x 1.65″) and weighs 185 g (0.41 lb / 6.53 oz) (including batteries).
Below you can see the front view size comparison of Samsung NX100 and Nikon S31. Nikon S31 is 15mm narrower and 6mm shorter than Samsung NX100 but it is also 7mm thicker. As you can tell, actually this is not a fair size comparison since Nikon S31 has a built-in lens but Samsung NX100 doesn't. Once you put a lens on NX100, its thickness will increase significantly.

Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon S31 is significantly lighter (97g ) than the Samsung NX100 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on NX100, the total kit will weigh much higher.

LCD Screen Size and Features
Samsung NX100's 3" LCD screen is slightly larger than Nikon S31's 2.7" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
Samsung NX100 has a 15.0MP APS-C (23.4 x 15.6 mm ) sized CMOS sensor and features DRIMe Engine processor. On the other hand, Nikon S31 has a 10.0MP 1/2.9" (4.96 x 3.72 mm ) sized CCD sensor .
Samsung NX100's sensor provides 5MP more than Nikon S31's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
Below you can see the NX100 and S31 sensor size comparison.
