Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Samsung NX210 is significantly lighter (273g ) than the Samsung Galaxy NX 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 also have to take into account the lenses that you will be using with these bodies. Since both Samsung NX210 and Samsung Galaxy NX have the same Samsung NX lens mount and APS-C sized sensors, lenses will not be a differentiator on total size of the system.
Weather Sealing
Unfortunately neither the Samsung NX210 nor Samsung Galaxy NX provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Samsung Galaxy NX's 4.80" LCD screen is slightly larger than Samsung NX210's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
