Oops, that example didn't quite work out LOL. If you consider the category of pointed sets, then it singletons are initial. Sorry, my bad. You do get different behaviour, though, when restricting to a suitable subcategory. If you take the category of groups, and restrict it to the full subcategory of abelian groups, you get an abelian category which the category of groups is not.
