> So I imagine the average Korean must be quite in conflict when buying a smartphone - the recognized international symbol of smartphone prestige and luxury (the iPhone) vs the nationalistic Galaxy.

I think you mean the one flavour of international symbol of smartphone prestige (Samsung Galaxy) vs another flavour of international symbol of smartphone prestige (iPhone).

Outside silicon valley, Android is actually quite well perceived and you're not looked at as an hobo or weirdo for using anything not an iPhone.

It may be hard to believe, but try to think differently every once in a while ;)
