You may of course change a singleton, but changes to it are obviously global to your app. If that's not what you want, then you don't want a singleton.

But you might! The singleton class pattern isn't synonymous with static configuration. There are other uses for singletons.

Yeah sure, but in an OO-environment that means you're breaking encapsulation. Singletons don't.

Tell me how do singleton's break encapsulation any more/less than a set of package variables? If you're using them to return static configuration information (as you seem to be proposing) then they encapsulate exactly the same thing.
