Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Samsung NX100 is significantly lighter (210g ) than the Sony A58 which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since both Samsung NX100 and Sony A58 have the same APS-C sized sensor, their lenses for a similar focal length and aperture will be similar in size and weight.

LCD Screen Size and Features
Samsung NX100's 3" LCD screen is slightly larger than Sony A58's 2.7" screen.
On the other hand, Sony A58 LCD screen has a
Tilting feature where you can change the angle of the screen to make it easier to shoot from waist or over the head levels. On the other hand, Samsung NX100 has a fixed type screen which provides less flexibility in shooting positions compared to A58.

Sony A58's sensor provides 5MP more than Samsung NX100'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.
