LCD and Viewfinder
Nikon S31 has a Fixed Type 2.7" LCD screen with a resolution of 230k dots. At only 2.7", the screen is on the smaller side and 230kdot resolution is lower than most of the recent models in this class.
S31 doesn't have a viewfinder and no option for external viewfinder. Lack of a viewfinder can be problematic especially under strong light where visibility of LCD screens goes down dramatically. If you need a Compact camera with a built-in viewfinder in a similar price range, consider Sony Cyber-shot DSC-H50 (Compare) or Canon PowerShot SD780 IS (Digital IXUS 100 IS) (Compare).
