Hindi doesn't have capital letters either. I think we recognize a name more by it's context than the case of the first letter. If I found a hindi word I didn't recognize, I would still be able to tell if it were a name or not. Perhaps caps exist for purely stylistic reasons. I wonder what would happen if someone did a design study of showing all caps vs sentence case text to people who have never seen English. Wonder which one would they say looks better.
